Problem: “P’s” Fast Food Restaurant

Mr. and Mrs. Johnson are planning a party for their daughter Samantha. They're buying the desserts for the party from P's fast food restaurant. They have a limit on how much they want to spend. The limit is $73.50. They are buying four different items.

The choices are:

-P's Famous Chocolate Cake- $14.50

-New York Style Cheese Cake-$26.00

-Dessert Bar Trays-$25.00

-Chocolate Eclair Cake-$20.00

-Tiramisu-$23.99

-Gourmet Brownie Tray-$14.00

-Mixed Treasures Tray-$15.00

-Chocolate Lovers Tray-$13.50

What did they choose to equal $73.50 exactly?

Answer:

P's Famous Chocolate Cake, Dessert Bar Trays, Chocolate Eclair Cake and Gourmet Brownie Tray.

How to find the answer:

In order to get the answer to our problem, you have to guess and test a couple of times to see if it matches the money the Johnson’s had to spend. You know that the change has to equal $ .50 for the total cost of the deserts, so Tiramisu cannot be one of the desserts because Tiramisu is $23.99. You can guess and test for the right dessert prices to equal up to $73.50. Another way to find the answers is to start with $73.50 and subtract four dessert prices to get to $0.00.
