At the start of the week, crystal’s bank account had a balance of $280. each day from monday to friday, she used her debit card to pay $5 for parking. she wrote a check for $42, and made two deposits of $75 each. she also withdrew $200 in cash at an atm. what was crystal’s balance at the end of the week?

 Crystal started with $280.

Monday - Friday is 5 days, in which she withdraws $5 each day for parking
5 x 5 = 25.

280 - 25 = $255 left.

She then wrote a check for $42

255 - 42 = $213 left.

She then deposited 2 $75 checks
213 + (75 + 75) = 
213 + 150 = 
$363 left

Crystal then withdrew $200 at the ATM
363 - 200 = $163

Crystal has $163 at the end of the week

hope this helps
