During one week, Sheila made several changes to her bank account. She made four

withdrawals of $40 each from an ATM. She also used her check card for a $156
purchase. Then she deposited her paycheck of $375.

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

1 answer

Sheila made a total of four withdrawals of $40 each, so she withdrew 4 * $40 = $160.
She also made a purchase of $156 using her check card.
So the total amount she spent is $160 + $156 = $316.

Sheila also deposited her paycheck of $375.

Therefore, the change in the amount in her bank account during that week is $375 - $316 = $59.

So the amount in her bank account increased by $59 during that week.
