Question

The cost C (in dollars) of producing x cell phone cases is C=2.2x+10.6. The revenue R (in dollars) for selling x cell phone cases R = 6.91x.

To calculate profit, subtract the cost from the revenue.
(a) Write and simplify an equation for the profit P in terms of x.
P = ?

Answer 1

P =4.71x-10.6

Explanation:

R = 6.91x

C=2.2x+10.6.

P = R - C = 6.91x-2.2x -10.6 =4.71x-10.6
