Suppose that the demand for Colin's kidney pies is linear in the price P. Determine the demand function N as a function of P giving the number of pies sold when the price is P if he can sell 100 pies when the price is $5.00 and he can sell 40 pies when the price is$10.00. Determine the revenue
(N×P)
for prices P = 5, 6, 7, 8, 9, 10 and then choose a price to maximize the revenue.
