SOLUTION

Write the information in the question

[tex]\begin{gathered} \text{Total amount in account= \$129} \\ \text{Total amount spend = \$}157 \end{gathered}[/tex]

To obtain the balance in the checking account, we subtract

Hence

[tex]\text{ \$129-\$157=-\$28}[/tex]

Hence

Mary will be having a new balance of - $28 in her checking account
