Answer:
Ethan's balance at the end of the week is of $273.75.
Step-by-step explanation:
Ethan starts the week with a balance of $275.00 in his checking account.
This means that B = 275.
During the week, he uses his debit card to spend $27.50 on food, $12.00 at the movies, and $6.75 for music downloads.
This is subtracted from the balance. So
B = 275 - (27.50 + 12 + 6.75) = 228.75
He earns and deposits $45.00 for mowing lawns.
Adds 45, so
B = 228.75 + 45 = 273.75
Ethan's balance at the end of the week is of $273.75.
