Fox Jeans regularly sells for $15 a pair and Pony jeans regularly sell for $18 a pair. During a sale these regular unit prices are discounted at different rates so that a total of $9 is saved by purchasing 5 pairs of jeans: 3 pairs of Fox jeans and 2 piars of Pony jeans. if the sum of the two discounts rates is 22 percent, what is the discount rate on Pony jeans?
sorry its 3am here
Thanks for the changes. Here is my answer.
3 Fox jeans before discount - 45$
2 pony jeans before discount - 36$
Let x be the discount for FJ and y be the discount for PJ.
45 * (X/100) + (36 * Y/100) = 9
X + Y = 22
.45 X + (.36 (22 - X)) = 9
.45 X + 7.92 - .36X = 9
.09 X = 1.08
X = 12 and Y = 10
Hence Discount for PJ = 10%
