Answer:
P(x) is the profit amount from selling tickets.
P(100) = $160
Step By Step Explanation:
First, plug in r(x) and c(x) into the p(x) equation:
p(x) = r(x) - c(x)
p(x) = (10x) - (8x+40)
Then simplify it:
p(x) = 10x - 8x - 40 {just distribute a +1 into the parentheses}
p(x) = 2x - 40 {combine like terms}
Now substitute 100 for x:
p(100) = 2(100) - 40
Then solve:
p(100) = 200 - 40
p(100) = 160
