For this case we must find the value of "x" of the following expression:

Multiplying by 2 on both sides of the equation:

Subtracting 8x from both sides of the equation:

Answer:

R = 16 according to the problem, so the total amount of income will be:
$20*16 + $15*(40 - 16)
= $320 + <span>$15*(24)

= $680
that is the income, but the expenses are $275 so the total revenue is the subtraction of those two
total revenue = $680 - $275
= $405</span>
