Question

Rob borrows $15.00 from his father, and then he borrows $3.00 more.

Drag numbers to write an equation using negative integers to represent Rob's debt and complete the
sentence to show how much money Rob owes his father. Numbers may be used once, more than once, or not at all.

Answer 1

rob owes his dad $13.00

Answer 2

-15 - 3 = -18

Rob owes his father 18 dollars.

Explanation:

If he borrowed 15 dollars from his dad, then 3 more, he borrowed a total of 15 + 3 dollars. That means he borrowed a total of 18 dollars. When you borrow money, you owe people, and after you spend the borrowed money it's like subtracting money from your 0 dollars. 0 - 18 = -18. He needs to earn 18 more dollars to pay back his father and get a balance of 0 dollars again.

Hope this helps.
