During one week, Sheila made several changes to her bank account. She made 4 withdrawals of $40 each from an ATM. She also used her check card for a $156 purchase. She then deposited her paycheck of $375.

By how much did the amount in her bank account change during the week?

Sheila made 4 withdrawals of $40 each, so the total amount withdrawn from her account is 4 * $40 = $160.

She used her check card for a $156 purchase, so the total amount spent is $156.
She then deposited $375 from her paycheck.

To find out how much the amount in her bank account changed during the week, we can calculate the total change in the amount in her account as follows:

Total change = Total withdrawals + Total purchases + Total deposits

Total change = $160 + $156 + $375

Total change = $691

Therefore, the amount in Sheila's bank account changed by $691 during the week.

increase or descrease and is that correct

Apologies for the oversight. Let's correct the calculation.

To calculate the net change in Sheila's bank account during the week, we need to consider that withdrawals and purchases decrease the account balance while deposits increase it.

Total withdrawals = 4 * $40 = $160
Total purchases = $156
Total deposits = $375

Net change = Total deposits - (Total withdrawals + Total purchases)
Net change = $375 - ($160 + $156)
Net change = $375 - $316
Net change = $59

Therefore, the amount in Sheila's bank account increased by $59 during the week. Thank you for pointing out the mistake.
