Benny opened a bank account. He deposited $92.50 into his account every month for 10 months. He used $36.50 every month to pay for art lessons. After 10 months, he used 1/2 of the total money left in his account to go to a summer camp for artists. What is the total amount of money Benny spent to go to the summer camp?
If Benny deposits $92.50 every month and withdraws $36.50 every month, his net deposit each month is:
92.50 - 36.50 = 56
Benny does this for 10 months, so his balance after 10 months is:
56 * 10 = 560
Half of this is:
560/2 = 280
