For every good skirt that Zane sold, Zane earned $12. He sold defective skirts at a discount, which would cause him to lose $4 per defective skirt. In January, for every 29 skirts sold, 9 were defective. Zane earned $2040 from the skirts sold.
- How many more skirts sold were good than defective?
- How much less money did he earn because of the defective skirts?

(a)
Amount that Zane earned
= 240 u - 36 u
= 204 u
204 u = 2040
1 u = 2040 ÷ 204 = 10
Number of more skirts sold that were good than defective
= 20 u - 9 u
= 11 u
= 11 x 10
= 110
(b)
Number of defective skirts
= 9 u
= 9 x 10
= 90
Less amount earned for one defective jacket
= 12 + 4
= $16
Less amount earned because of all the defective skirts
= 90 x 16
= $1440
Answer(s): (a) 110; (b) $1440
