Let the discount of Fox jean = x
Let the discount of Pony jean = y

3(15x)+2(18y)=9 this is the total save from the puchase of 3 Fox jeans & 2 Pony jeans

x+y=0.22

From the 1st equation, we get 45x+36y=9, divide both size by 9 we get 5x+4y=1

Multiply the 2nd equation by 5, we get 5x+5y=1.1

Substract 1st equation from 2nd equation we get x=0.12, y=0.1

So the discount for the Pony jean is 10%

Correct me there is any mistake.

Yup, the discount for poly jeans is 10%. Answer is 'B'.

We form two equations

x+y=22
45x + 36y = 900

Solve them.
