Help please, You have a coupon for 10% off at a game store. If you paid $13.50 for game useing your coupon, how much did the game originally cost? Please show work ;)

OpenStudy (anonymous):

You paid 90 percent of the original cost so take $13.50 / 90. To get the original cost multiply the answer by 100.

OpenStudy (anonymous):

Don't understand. o-o.

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

So, 13.50 / 90 = 0.15 0.15*100 = $15 which is the original price.

OpenStudy (anonymous):
