The table shows Ava's checking account activity for several weeks. Ava's beginning balance was $685. What was her ending balance
Dafna11 [192]
B. Deposit means she added money to her account so you would add 175 and 180 to 685 (giving you 1040). Withdrawal means she took money out of her account so you would subtract 240, 140, and 350 from 1040 giving you your answer of $310 :)
