The manager of a hardware store sells batteries for $5 a package. She wants to see how much money she will earn if she increases the price
in 10¢ increments. A model of the price change is the revenue
function R(x) = – x2 + 10x + 3000, where x is the number of
10¢ increments and R(x) is in dollars. Explain how to determine the
maximum revenue.

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
