Let's calculate the current balance step by step using the given check register.
1. Starting Balance:
[tex]\[
\$82.92
\][/tex]
2. Subtract the Monthly Fee (5/1):
[tex]\[
\$82.92 - \$8.00 = \$74.92
\][/tex]
The balance after the monthly fee is:
[tex]\[
\$74.92
\][/tex]
3. Subtract the Phone Bill (5/3):
[tex]\[
\$74.92 - \$78.24 = -\$3.32
\][/tex]
The balance after paying the phone bill is:
[tex]\[
-\$3.32
\][/tex]
4. Add Paycheck (5/15):
[tex]\[
-\$3.32 + \$125.00 = \$121.68
\][/tex]
The balance after depositing the paycheck is:
[tex]\[
\$121.68
\][/tex]
5. Subtract the ATM Withdrawal (5/17):
[tex]\[
\$121.68 - \$40.00 = \$81.68
\][/tex]
The balance after the ATM withdrawal is:
[tex]\[
\$81.68
\][/tex]
6. Subtract Tennis Lessons (5/20):
[tex]\[
\$81.68 - \$56.50 = \$25.18
\][/tex]
The balance after paying for tennis lessons is:
[tex]\[
\$25.18
\][/tex]
Therefore, the current balance is:
[tex]\[
\$25.18
\][/tex]
