Answer 1

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
