Answer:
13,000
$80
Explanation:
As per the data given in the question, the computation is shown below:
Market demand function Q = 18,000 - 100P + 11,000 - 100P
Q = 29,000 - 200P
Divide by 200
The inverse function P = 145 - (Q ÷ 200)
TR = P×Q = 145Q - 0.005Q^2
MR = 145 - (1 ÷ 100)
Q = 145 - 0.01Q
Marginal cost (MC) = 15
At equilibrium MR = MC
145 - 0.01Q = 15
Q = 13,000
P = 145 - 0.005 × 13,000 = $80
