Janet is an artist who produces and sells prints of her artwork. If Janet sells her prints for $17 each, then she will sell 340 prints. Janet is considering whether she should change the price. She takes a survey and concludes that for each price increase of 75 cents, she will sell 10 fewer prints.(adsbygoogle = window.adsbygoogle || []).push({});

1. Janet plans to produce exactly the number of prints that her survey predicts she will sell. Her costs include $2 per print, along with $500 in ﬁxed costs. Find a formula for C(x), Janet’s total costs, in terms of x, the number of 75 cent price increases.

A: C(x) = 500 + 2(340 − 10x)

2. Find a formula for Janet’s revenue, R(x), in terms of x, the number of 75 cent

price increases.

A: R(x) = (17 + 0.75x)(340 − 10x)
