Ind 5. A food truck finds that each time they increase the price of burritos by $0.50 they sell 60
fewer burritos per day on average, as shown in the following table:
Price, p (in dollars) Number of burritos sold, B
5.50
740
6.00
680
6.50
620
7.00
560
(a) Find an equation that expresses the number of burritos sold, B, in terms of the selling
price, p.
(b) Use your equation to determine: How many burritos would be sold at a price of $4.25?
(c) What should the selling price should be in order to sell 900 burritos?
(d) According to this model, you could raise the price so much that zero burritos would be
sold. What is this price?
