Answer:
Total Amount in the checking account=S+8
Step-by-step explanation:
Total Amount in the checking account=Initial Amount in the checking account+Earnings from chores-Expenditure on movie tickets
where;
Initial amount in the checking account=S-15
Earnings from chores=38.5
Expenditure on movie tickets=Cost per ticket×Number of tickets=(7.75×2)=15.5
Replacing;
Total Amount in the checking account=(S-15)+38.5-15.5=S+38.5-15-15.5
Total Amount in the checking account=S+8
