For every good skirt that Ken sold, Ken earned $14. He sold defective skirts at a discount, which would cause him to lose $3 per defective skirt. In March, for every 20 skirts sold, 5 were defective. Ken earned $975 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 Ken earned
= 210 u - 15 u
= 195 u
195 u = 975
1 u = 975 ÷ 195 = 5
Number of less skirts sold that were defective than good
= 15 u - 5 u
= 10 u
= 10 x 5
= 50
(b)
Number of defective skirts
= 5 u
= 5 x 5
= 25
Less amount earned for one defective jacket
= 14 + 3
= $17
Less amount earned because of all the defective skirts
= 25 x 17
= $425
Answer(s): (a) 50; (b) $425
