Answer:  14
<u>Step-by-step explanation:</u>
f(x) = 3x + 2
To find f⁻¹, swap the x's and y's and solve for y --> Note: f(x) is y
x = 3y + 2
x - 2 = 3y





f(f⁻¹(14)) = f(4)
               f(4) = 3(4) + 2
                      = 12 + 2
                      = 14
NOTE: the simplified version is .... f and f⁻¹ cancel out, leaving you with 14

She bought 4 Movies and 3 CDs so she spend $19.50 bc 3+3+3+3=12 so 2.50+2.50+2.50=7.50 so 7.50+12=19.50
