Chapter 4.7, Problem 12G

From years of experience, the owner of a small boutique has found that she can sell $x=300$

paris of earrings per month when she charges $p=\$15$

per pair. She’s able to sell 375 pairs per month at a price of $12 per pair.

With profits soaring due to your economic expertise, the boutique owner decides to open a second location, and finds that the profit equation for selling earrings at the second location is $P=–0.05x^2+22x-450$. Write a single equation that describes the combined profit on earrings for both locations.
