1) P= 0.005y^2-0.02y+122
Plug in 40 to y and solve.
P=129.2

2) P=0.005y^2-0.02y+122
Plug in 132.56 for P and solve.
This came be solved by moving the terms to the left side and setting everything equal to 0. After you combine like terms and factor to get:

(y+44)=0
(y-48)=0

Y=-44 and Y=48

Age cannot be negative so the answer must be 48.
