Answer

Explanation:

Step1: Analyze no - 8% earnings months

January and February have sales less than $20000. So, no 8% commission as 8% commission is for sales greater than $20000.

Step2: Find other non - 8% month

June has sales of $14259 which is less than $20000, so it has no 8% earnings.

Step3: Calculate for March

Sales over $20000 for March: $25175 - 20000=5175$. 5% commission on first $20000 is $20000\times0.05 = 1000$. 8% commission on $5175 is $5175\times0.08=414$. Total earnings: $900 + 1000+414 = 2314$.

Step4: Calculate for May

Sales over $20000 for May: $28317 - 20000 = 8317$. 5% commission on first $20000 is $20000\times0.05=1000$. 8% commission on $8317 is $8317\times0.08 = 665.36$. Total earnings: $900+1000 + 665.36=2565.36$.

Step5: Calculate for August

Sales over $20000 for August: $27635 - 20000=7635$. 5% commission on first $20000 is $20000\times0.05 = 1000$. 8% commission on $7635 is $7635\times0.08=610.8$. Total earnings: $900+1000 + 610.8=2510.8$.

Step6: Calculate for September

Sales over $20000 for September: $29452 - 20000 = 9452$. 5% commission on first $20000 is $20000\times0.05=1000$. 8% commission on $9452 is $9452\times0.08 = 756.16$. Total earnings: $900+1000+756.16 = 2656.16$.

Step7: Calculate for December

Sales over $20000 for December: $31257 - 20000=11257$. 5% commission on first $20000 is $20000\times0.05 = 1000$. 8% commission on $11257 is $11257\times0.08=900.56$. Total earnings: $900+1000+900.56 = 2800.56$.

Step8: Total earnings

Sum all total earnings values: $1812.25+1872.50 + 2314+2235.92+2565.36+900+2066.56+2510.8+2656.16+2273.92+2642.8+2800.56$ $=26651.73$.

Answer:

a) Because sales in January ($18245) and February ($19450) are less than $20000, so no 8% commission on sales greater than $20000. b) June, as sales ($14259) is less than $20000. c)
