I think this is a good example where you can use the backsolve approach.

You know that Fox jeans costs $15, and Pony jeans costs$18, you also know that 3 pairs of Fox jeans and 2 pairs of Pony jeans were purchased. So

3(15) = 45 - Fox
2(18) = 36 - Pony

The total discount discount is $9 and you are asked to find the percent discount of pony jeans, so 45(.22 - .X) + 36(.X) = 9 here you can plug in numbers starting with C, 45(.22-.11)+36(.11) = 4.95 + 3.96 = 8.91 not = 9, eliminate Move to B, as C was too small a number so the discount should be at a greater percentage for Fox jeans because we've purchased 3 pairs.. 45(.12) + 36(.10) = 9 and we've got our answer.

I tried the backsolve approach . I first tried with 10% and as the number was easy got the answer.

But Venks, when I see your solution, I realize how foolish Iam.

You guyz are just too good. Everyday is a new learning for me.

x discount on Pony jeans, (0.22-x) discount on Fox jeans.

Set the equation: 3*15(0.22-x)+2*18x=9 --> x=0.1=10%

Answer: B.
