The revenue for a small business is modeled by the function R(x) = 5x where represents the number of items soldThe cost function

MAVERICK [17]

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

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

$P(x) = 3x - 10$
