Economy drapes for a certain size window cost $90. They have shallow pleats,
and the width of the fabric is 2 times the window width. Luxury drapes of the same fabric for the same size window have deeper pleats. The width of the fabric is 3 times the window width. What price should the store manager ask for the luxury drapes?

Cross multiply and solve for x.

90/2 = x/3
