Question

1. the total cost for printing ( x ) copies of a book is $200 plus $2.50 per copy. which equation represents the total cost (( c ))?

a. ( c = 200 + 2.50x )
b. ( c = 200 - 2.50x )
c. ( c = 200x + 2.50 )
d. ( c = 200 \times 2.50 )

Explanation:

Step1: Identify fixed cost

Fixed cost = $\$200$

Step2: Calculate variable cost

Variable cost = $2.50x$ (cost per copy × number of copies)

Step3: Sum costs for total $C$

$C = \text{Fixed cost} + \text{Variable cost} = 200 + 2.50x$

Answer:

a. $C = 200 + 2.50x$
