You idiot you answered your own question!
The percent discount is 30%.
If you multiply $32 by .30, you will get $9.60. That is the amount of the discount. If you subtract $9.60 from $32, you will get $22.40 which is what he paid before tax. Therefore the percent discount is 30%.
3/4 of 120
=3/4*120
=360/4
=90
3/8 of 160
=3/8*160
=480/8
=60
Well there are 8 in 1/8 so you multiply that but three and you get 24
The answer is 24
