736

Right.

To find out how much Rowan raised this year, you need to calculate 15% of the amount he raised last year and then add it to last year's total amount.

First, calculate 15% of $640:
15% = 15/100 = 0.15
15% of $640 = 0.15 * $640 = $96

Next, add the amount raised last year ($640) and the 15% increase ($96):
$640 + $96 = $736

Therefore, Rowan raised $736 this year.
