Joseph has a balance of −$20 in his checkbook. If he deposits $135 and then writes a check for $55, what is the new balance in his checkbook?The checkbook balance is $

SOLUTION:
Given the question in the question tab, the following is the solution to the question
Step 1: We write the statements in mathematical forms and execute the first operation.
Let the initial balance be $-20, if he deposits $135, this means that this amount was added to his checkbook. Hence, the new account becomes:
[tex]\text{\$}-20+\text{\$}135=\text{\$}115[/tex]Step 2: He then writes a check for $55, this is a withdrawal and therefore a deficit. We now have:
[tex]\text{\$}115-\text{\$}55=\text{\$}60[/tex]Hence, the new balance in his checkbook will be $60.
