I posted this earlier, but got no answer. So I am re-posting.

Jean deposited a check for $625, wrote two for $68.74 and
$29.95 and used her debit card to pay for a purchase of $57.65. How has her
account balance changed?

I am a little lost, I understand the deposit BUT from what I understand she wrote 2 check in the amount of $68.74 each and then 2 checks for $29.95 and then used her debet card for $57.65?
Or was it just 2 checks all together 1 for $68.74 and 1 for $29.95 and then used her debet card for $57.65?

Her account was credited (went up) by $625.00 and was debited (went down) by $156.34 (<~~29.95 + 68.74 + 57.65).

So subtract the smaller number from the larger. How did the account change overall? Did it increase or decrease?

(Without knowing the original balance, there's no way to know what the ending balance is.)

To calculate how Jean's account balance has changed, we need to add up all the debits and subtract them from the initial credit. From the information provided, Jean deposited $625 into her account. She then wrote two checks, one for $68.74 and another for $29.95. Finally, she made a purchase using her debit card for $57.65.

So, to calculate the change in her account balance, we need to subtract the total amount of all the debits ($68.74 + $29.95 + $57.65) from the credit ($625.00).

$68.74 + $29.95 + $57.65 = $156.34

$625.00 - $156.34 = $468.66

Therefore, Jean's account balance has changed by $468.66. However, without knowing the original balance, we can't determine the final balance.
