Idon't know how to solve this problem!
"jacob earned $80 babysitting and deposited the money into his savings account. the next week he spent $85 on video games. use integers to describe the weekly changes in jacobs savings account balance.

it will be greatly

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!!
