With a coupon, you can get a pair of shoes that normally costs $84 for only $71.40. What percentage was the discount? *
Ok so you have to divide 71.40 by 84, then you multiply the result by 100 to get a percentage.
71.40 / 84= 0.85
0.85*100= 85%
Edit: I forgot to subtract it from 100%. The answer would be 15%. :)
