Kelly had S-15 in her checking account. She did a few chores and made 38.50. She decided to pay for her and a friend to go t on the movies, and each ticket cost 7.75 how much money does she have in her checking account?

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
