For every good skirt that Wesley sold, Wesley earned $25. He sold defective skirts at a discount, which would cause him to lose $2 per defective skirt. In August, for every 30 skirts sold, 10 were defective. Wesley earned $1440 from the skirts sold.
- How many less skirts sold were defective than good?
- How much less money did he earn because of the defective skirts?

(a)
Amount that Wesley earned
= 500 u - 20 u
= 480 u
480 u = 1440
1 u = 1440 ÷ 480 = 3
Number of less skirts sold that were defective than good
= 20 u - 10 u
= 10 u
= 10 x 3
= 30
(b)
Number of defective skirts
= 10 u
= 10 x 3
= 30
Less amount earned for one defective jacket
= 25 + 2
= $27
Less amount earned because of all the defective skirts
= 30 x 27
= $810
Answer(s): (a) 30; (b) $810
