Let C ( q ) represent the cost and R ( q ) represent the revenue, in dollars, of producing q items. Suppose C ( 100 ) = 4000 and R ( 100 ) = 5500. If C ′ ( 100 ) = 20 and R ′ ( 100 ) = 24, approximately how much profit is earned by producing 101 items?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
