Answer

Explanation:

Step1: Define Break - Even Formula

To break even, the total revenue (from album sales) must equal or exceed the total cost. The total cost ( C ) includes the fixed cost of acquiring the album rights (( $148,950 )), the variable production cost (cost per album times number of albums sold, ( 1.13\times n ), where ( n ) is the number of albums sold), and the overhead expenses (( E )). The total revenue ( R ) is the selling price per album times the number of albums sold (( 9.75\times n )). So, the break - even condition is ( 9.75n\geq148950 + 1.13n+E ), which can be rewritten as ( 9.75n-1.13n\geq148950 + E ), or ( 8.62n\geq148950 + E ).

Step2: Calculate for January

For January: ( n = 5486 ), ( E=$27714 ) First, calculate the left - hand side: ( 8.62\times5486=8.62\times5000 + 8.62\times486=43100+4190.32 = 47290.32 ) Calculate the right - hand side: ( 148950 + 27714=176664 ) Since ( 47290.32<176664 ), January does not break even.

Step3: Calculate for March

For March: ( n = 4796 ), ( E = 25195 ) Left - hand side: ( 8.62\times4796=8.62\times(4000 + 700+96)=8.62\times4000+8.62\times700 + 8.62\times96=34480+6034+827.52=34480 + 6034=40514+827.52 = 41341.52 ) Right - hand side: ( 148950+25195 = 174145 ) Since ( 41341.52<174145 ), March does not break even.

Step4: Calculate for April

For April: ( n = 7490 ), ( E = 28766 ) Left - hand side: ( 8.62\times7490=8.62\times(7000 + 490)=8.62\times7000+8.62\times490=60340+4223.8 = 64563.8 ) Wait, no, we made a mistake in the formula. Let's re - derive the total cost and total revenue correctly.

Total cost ( C=148950 + 1.13n+E ) Total revenue ( R = 9.75n ) Break - even when ( R\geq C), so ( 9.75n\geq148950+1.13n + E) ( 9.75n-1.13n\geq148950 + E) ( 8.62n\geq148950 + E)

For April: ( n = 7490 ), ( E = 28766 ) ( 8.62\times7490=8.62\times7000+8.62\times490=60340 + 4223.8=64563.8 ) ( 148950+28766 = 177716 ) Wait, that's still not right. Wait, we messed up the fixed cost. The fixed cost of ( $148,950 ) is a one - time cost? Wait, no, the problem says "at the beginning of January, Kesia Records paid $148,950 to acquire the exclusive rights". So this is a fixed cost that is spread over the months? Wait, no, maybe we should consider cumulative sales and cumulative costs.

Let's re - approach. Let's calculate cumulative albums sold, cumulative production cost, cumulative overhead, and cumulative revenue.

Let's define:

  • Fixed cost (acquisition): ( F = 148950 )
  • Variable cost per album: ( v = 1.13 )
  • Selling price per album: ( s=9.75 )
  • Overhead per month: ( E_m ) (given in the table)

Cumulative number of albums sold by month ( m ): ( N_m=\sum_{i = 1}^{m}n_i ) (where ( n_i ) is the number of albums sold in month ( i ))

Cumulative production cost: ( V_m=v\times N_m )

Cumulative overhead: ( O_m=\sum_{i = 1}^{m}E_i )

Total cost: ( C_m=F + V_m+O_m )

Total revenue: ( R_m=s\times N_m )

Break - even when ( R_m\geq C_m )

Let's calculate step by step for each month:

January:

( N_1 = 5486 ) ( V_1=1.13\times5486 = 5486\times1+5486\times0.13=5486 + 713.18 = 6199.18 ) ( O_1 = 27714 ) ( C_1=148950+6199.18 + 27714=148950+33913.18 = 182863.18 ) ( R_1=9.75\times5486=5486\times9 + 5486\times0.75=49374+4114.5 = 53488.5 ) ( 53488.5<182863.18 ), not break even.

February:

( N_2=5486 + 8191=13677 ) ( V_2=1.13\times13677=13677\times1+13677\times0.13=13677+1778.01 = 15455.01 ) ( O_2=27714 + 21689=49403 ) ( C_2=148950+15455.01+49403=148950 + 64858.01=213808.01 ) ( R_2=9.75\times13677=13677\times9+13677\times0.75=123093+10257.75 = 133350.75 ) ( 133350.75<213808.01 ), not break even.

March:

( N_3=13677 + 4796=18473 ) ( V_3=1.13\times18473=18473\times1+18473\times0.13=18473+2401.49 = 20874.49 ) ( O_3=49403+25195 = 74598 ) ( C_3=148950+20874.49+74598=148950+95472.49 = 244422.49 ) ( R_3=9.75\times18473=18473\times9+18473\times0.75=166257+13854.75 = 180111.75 ) ( 180111.75<244422.49 ), not break even.

April:

( N_4=18473+7490 = 25963 ) ( V_4=1.13\times25963=25963\times1+25963\times0.13=25963+3375.19 = 29338.19 ) ( O_4=74598+28766 = 103364 ) ( C_4=148950+29338.19+103364=148950+132702.19 = 281652.19 ) ( R_4=9.75\times25963=25963\times9+25963\times0.75=233667+19472.25 = 253139.25 ) Wait, still not enough. Wait, maybe we made a mistake in considering the fixed cost. Wait, the $148,950 is a one - time cost, and then each month we have production cost and overhead. Maybe we should calculate the profit (revenue - (production cost + overhead)) and see when the cumulative profit (including the fixed cost) is non - negative.

Profit per month (before considering the fixed cost): ( P_m=(s - v)n_m-E_m=(9.75 - 1.13)n_m-E_m=8.62n_m-E_m )

Cumulative profit (including the fixed cost): ( CP_m=\sum_{i = 1}^{m}(8.62n_i - E_i)-148950 )

We need ( CP_m\geq0 )

January:

( P_1=8.62\times5486-27714=47290.32 - 27714 = 19576.32 ) ( CP_1=19576.32-148950=- 129373.68 ) (negative, not break even)

February:

( P_2=8.62\times8191-21689=70606.42-21689 = 48917.42 ) ( CP_2=-129373.68 + 48917.42=-80456.26 ) (negative)

March:

( P_3=8.62\times4796-25195=41341.52-25195 = 16146.52 ) ( CP_3=-80456.26+16146.52=-64309.74 ) (negative)

April:

( P_4=8.62\times7490-28766=64563.8 - 28766 = 35797.8 ) ( CP_4=-64309.74+35797.8=-28511.94 ) (negative) Wait, this is not right. Wait, maybe the fixed cost is amortized? No, the problem says "paid $148,950 to acquire the exclusive rights" which is a fixed cost. Wait, maybe we miscalculated the profit formula.

Wait, total revenue from sales: ( R = 9.75n )

Total cost: ( C = 148950+1.13n+E ) (where ( E ) is the overhead for the month)

So profit ( \pi=R - C=9.75n-(148950 + 1.13n+E)=8.62n - E - 148950 )

We need ( \pi\geq0 ), so ( 8.62n\geq E + 148950 )

Let's calculate for each month:

January: ( n = 5486 ), ( E = 27714 ) ( 8.62\times5486=47290.32 ), ( E + 148950=27714 + 148950 = 176664 ), ( 47290.32<176664 )

February: ( n = 5486 + 8191=13677 ), ( E = 27714+21689 = 49403 ) ( 8.62\times13677=117995.74 ), ( E + 148950=49403+148950 = 198353 ), ( 117995.74<198353 )

March: ( n = 13677+4796 = 18473 ), ( E = 49403+25195 = 74598 ) ( 8.62\times18473=159237.26 ), ( E + 148950=74598+148950 = 223548 ), ( 159237.26<223548 )

April: ( n = 18473+7490 = 25963 ), ( E = 74598+28766 = 103364 ) ( 8.62\times25963=223801.06 ), ( E + 148950=103364+148950 = 252314 ), ( 223801.06<252314 )

May: ( n = 25963+6272 = 32235 ), ( E = 103364+24604 = 127968 ) ( 8.62\times32235=277865.7 ), ( E + 148950=127968+148950 = 276918 ) Now, ( 277865.7>276918 ), so in May, the profit is positive? But the options are January, March, April, May. Wait, maybe we made a mistake in cumulative sales.

Wait, the problem says "in which month did Kesia Records first break even". Maybe the fixed cost is a one - time cost, and we calculate the total cost as the sum of the acquisition cost, production cost (for the month), and overhead (for the month), and total revenue as sales for the month.

So for each month, total cost ( C = 148950+1.13n+E ), total revenue ( R = 9.75n )

We need to find the first month where ( R\geq C )

January: ( R = 9.75\times5486 = 53488.5 ) ( C = 148950+1.13\times5486+27714=148950 + 6199.18+27714 = 182863.18 ) ( 53488.5<182863.18 )

February: ( R = 9.75\times8191 = 79862.25 ) (wait, no, cumulative sales? No, maybe the problem is that the $148,950 is a fixed cost, and we calculate the profit each month as (revenue from sales - production cost - overhead) and see when the cumulative profit (including the fixed cost) is zero or positive.

Let's calculate cumulative profit:

January: Profit from sales: ( 9.75\times5486-1.13\times5486
