Question

I don't know how to solve this problem!

Answer 1

So the amount of money he earned is a  positive integer, and the amount of money he spent is a negative integer.
he earned $80, so that's positive, he spent $85,so that's negative. his savings account balance in -$5 since he went over the amount of money he actually made. so his balance is a negative integer.
hope u found that helpful!!

Answer 2

The integers will be $ 5 but they only had $80 so that is my answer
