485-2(15)

485-30= 455

Answer:  6825

==============================================

Work Shown:

[tex]R(x) = x*P(x)\\\\R(x) = x*(485-2x)\\\\R(15) = 15*(485-2*15)\\\\R(15) = 6825\\\\[/tex]

Explanation:

The revenue is the money coming into the company. It's before expenses are calculated. Revenue is found by multiplying number of units x with the price per unit p(x).

For example, if a radio sells for $7 each and you sold 10 of them, then the revenue is 7*10 = 70 dollars. So this explains why R(x) = x*p(x)

Afterward, replace every x with 15 and simplify. Use a calculator if needed.
