Example Question #51 : Percentage
A fundraiser for a local charity raised $28,000 in donations last year. The fundraiser’s goal for this year is to exceed last year’s donations by 15%. So far, they have raised $31,000. How much more money must the fundraiser raise to reach their goal?
$5500
$1200
$4200
$3200
$1500
$1200

Since $31,000 has been raised so far, the amount remaining is as follows:
