klasskru [66]

Answer:

P(x) = -0.25x^2 + 42x - 90

Step-by-step explanation:

Given

C(x) = -17x + 90

R(x) =- 0.25x^2 + 25x

Required

Determine the profit function.

Profit function is calculated as thus:

P(x) = R(x) - C(x)

So, we have:

P(x) = -0.25x^2 + 25x -(-17x + 90)

P(x) = -0.25x^2 + 25x + 17x - 90

P(x) = -0.25x^2 + 42x - 90
