Question from Vanessa, a parent:

Mrs Henderson buys a chair for $215.00 and later sell the chair for $336.00 what percent profit is this?

Hi Vanessa,

The profit is $336.00 - $215.00 = $121.00. Percent profit means to express the profit as a percentage of what the chair cost you. The profit as a fraction of what it cost you is $121.00/$215.00 = 0.5628. To express this fraction as a percentage you multiply by 100 to get 56.28%.
