Question

Michelle works at a store that sells clothing accessories. The supply function for baseball caps is P=Q-6, where P is the price and Q is the quantity of baseball caps. If Michelle sells the baseball caps for $19 apiece, how many baseball caps will the store make?

A. 31 baseball caps
B. 6 baseball caps
C. 19 baseball caps
D. 25 baseball caps

Answer 1
