Eva opened a bank account. She deposited $68.40 into her account every month for 20 months. She used $42.40 every month to pay for craft classes. After 20 months, she used 1 over 2 of the total money left in her account to go to a crafting summer camp. What is the total amount of money Eva spent to go to the summer camp?

$131.00

$137.00

$179.00

$260.00

What is the answer?

I think $260.00 because she deposited $68.40 each month but uses $42.40 every month for classes. So $68.40 – $42.40 = $26.00 is being deposited each month. 26 • 20 = 520 = $520 from 20 months. Then it says after 20 months she uses half of it to go to summer camp so 520 / 2 = 260.
