2 answers:
For this case we have the following equation:
Where the variable "x" represents the cost of a performance ticket.
Clear "x" of the equation to know the cost of a ticket.
Subtracting 12 on both sides of the equation:
Dividing between 4 on both sides of the equation:
So, the cost of a ticket is $ 9.00

Answer:
(a) Profit function P(x) = 0.02x^2+60x-80
(b) Average profit P(x)/x = P/x = 0.02x+60-80/x
Marginal profit dP/dx = 0.04x+60
Step-by-step explanation:
Cost function: C(x) = -0.02x^2+40x+80
Price function: p(x) = 100
(a) The profit function P(x) = x*p(x)-C(x) can be expressed as:
(b)Average profit function: P(x)/x
Marginal profit function: dP/dx
