Answer 1

Rolex wrote a check for $45

The next day, he wrote a check for $32

We are asked to use an integer to express the change in his bank balance when the two checks were cashed.​

When the two checks were cashed means that that much amount was subtracted from his account.

So we can write the change in his bank account as

`-\$45+(-\$32)=-\$45-\$32=-\$77`

Therefore, -$77 is the change in his bank balance when the two checks were cashed.
