At lunch time, Ben often borrows money from his friends to buy snacks in the school cafeteria. He borrowed $1.75 from his friend Clyde each day for five days last week to buy ice cream. Represent the amount he borrowed as the product of two rational numbers; then determine how much Ben owed his friend.

Step-by-step explanation:

Ben often borrows money from his friends to buy snacks in the school cafeteria. He borrowed $1.75 from his friend Clyde each day. Converting the amount borrowed from decimal to fraction, it becomes

1 3/4 = $7/4

He borrowed $7/4 each day and for 5 days,

Amount borrowed as a product of two rational numbers is 7/4 * 5/1 = $35/4

The amount that Ben owed his friend is 35/4 = $8.75
