Solution

Number Line: 1 Mark
Steps: 1 Mark
Answer: 1 Mark

Money in the pocket can be taken as positive. Then the money owed will be negative.Presently Steve has 13butheowes5. Hence, money he actually has =13-5 = 8. The given number line shows the money Steve has.

Similarly, Michel owes 3,HenceactualmoneyMichelhas=13 - 3=10

Cooper has $13.

As we know that the number on the left side is smaller than the number on the right side, we can hence conclude that Steve is poorest and Cooper is richest.
