Answer:
price = $25
maximum profit is $2400
Step-by-step explanation:
Given the function modeled by the community theatre as
p(d)=−4d^2+200d−100
The maximum profit will be ,ade at dP/dd = 0
dP/dd = -8d + 200
0 = -8d + 200
8d = 200
d = 200/8
d = 25
hence he theatre will make maximum profit at a price of $25
Substitute d = 25 to get the maximum profit
p(25)=−4(25)^2+200(25)−100
p(25) = -2500+5000-100
p(25) = 2400
Hence the maximum profit is $2400
