Answer:
$92.50 * 10 =$925 ( deposited$92.50 into his account every month for 10 so we multiply)
$36.50*10 = $365 ( used $36.50 every month to pay art lessons every month means he took out)
925-365=560 ( total amt left in the account after taking out $365)
He used 1 over 2 of total money means
560/2 = 280
The answer would be B $280.
Hope this helps!!
