The manager of a bike store is setting the
price for a new model. Based on past sales
history, he predicts that if he sets the price
at $360, he can expect to sell 280 bikes this
season. He also predicts that for every $10
increase in the price, he expects to sell five
fewer bikes.
a) Write a function to model this situation.
b) What maximum revenue can the
manager expect? What price will give
that maximum?
c) Explain any assumptions involved in
using this model.
