Answer:

$P(x) = 16x - 100 - 0.1x^2$

Step-by-step explanation:

Given

$R(x) = 46x$

$C(x) = 100 +30x +0.1x^2$

Required

Determine the profit function

This is calculated as follows:

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

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

$P(x) = 46x - (100 + 30x + 0.1x^2)$

Open bracket

$P(x) = 46x - 100 - 30x - 0.1x^2$

Collect like terms

$P(x) = 46x - 30x - 100 - 0.1x^2$

$P(x) = 16x - 100 - 0.1x^2$
