Answer:
this is for ques 1.
a. to find number of customers for a price of 10$ per pie is, you put 10 in the given equation C(p) = 110-4.4x(10) = 110-44= 66.
so the revenue from 66 customers at a rate of 10$ will be 66x10 = 660$.
b. to find the equation for revenue you multiply the price p with the given equation for number of customers ie, PxC(p), when you do this you get the total price made fr the total number of customers.
we know equation for C(p), so we rewrite PxC(p),
P x (110 -4.4p) = 110P - 4.4p^2.
set 110p = 4.4p^2 and solve. we get 25 for p.
so the domain is (0, 25) because if you put a number greater than 25 in the revenue eqn you get negative.
