Answer:

P(x) = 3x - 10

Step-by-step explanation:

Given

R(x) = 5x

C(x) = 10 + 2x

Required

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

In functions;

(f - g)(x) = f(x) - g(x)

So, we have:

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

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

Substitute values for R(x) and C(x)

P(x) = 5x - (10 + 2x)

Open bracket

P(x) = 5x - 10 - 2x

Collect Like Terms

P(x) = 5x - 2x- 10

P(x) = 3x - 10
