For every good skirt that Simon sold, Simon earned $20. He sold defective skirts at a discount, which would cause him to lose $3 per defective skirt. In January, for every 23 skirts sold, 7 were defective. Simon earned $1495 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 Simon earned
= 320 u - 21 u
= 299 u
299 u = 1495
1 u = 1495 ÷ 299 = 5
Number of less skirts sold that were defective than good
= 16 u - 7 u
= 9 u
= 9 x 5
= 45
(b)
Number of defective skirts
= 7 u
= 7 x 5
= 35
Less amount earned for one defective jacket
= 20 + 3
= $23
Less amount earned because of all the defective skirts
= 35 x 23
= $805
Answer(s): (a) 45; (b) $805
