Lesson 15 Problem Set

At lunch time, Benjamin often borrows money from his friends to buy snacks in the school cafeteria.  Benjamin borrowed $0.75 from his friend Clyde five days last week to buy ice cream bars.  Represent the amount Benjamin borrowed as the product of two rational numbers; then, determine how much Benjamin owed his friend last week. 

• 5 times (-.75) = -3.75
• 5 plus (.75) = 5.75
• 5 times (.75) = 3.75
• 5 minus (-.75) = -4.25
