Question
- Hi, just to clarify, can you respond to me about the Math problem, a) and b). Just to clarify that there should be "two" answers for both "a)" and "b)". Thanks.

- Shawn earns $375 per week plus a commission of $7.5% on all sales. Calculate his weekly earning on sales of: a) $8000, and b) $12 500.

Answer
Yes, there should be 2 answers a) and b) since there are 2 cases to consider. His/her weekly earning is the sum of his weekly salary plus the commision he earns that week.

a) $375 + (7.5%/100)$8000 = $370 + (0.075)$8000 = $375 + $600 = $975.

b) $375 + (0.075)$12500 = $1312.50.
