For every good skirt that Zane sold, Zane earned $17. He sold defective skirts at a discount, which would cause him to lose $5 per defective skirt. In July, for every 22 skirts sold, 9 were defective. Zane earned $528 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 Zane earned
= 221 u - 45 u
= 176 u
176 u = 528
1 u = 528 ÷ 176 = 3
Number of less skirts sold that were defective than good
= 13 u - 9 u
= 4 u
= 4 x 3
= 12
(b)
Number of defective skirts
= 9 u
= 9 x 3
= 27
Less amount earned for one defective jacket
= 17 + 5
= $22
Less amount earned because of all the defective skirts
= 27 x 22
= $594
Answer(s): (a) 12; (b) $594
