For every good skirt that Cody sold, Cody earned $13. He sold defective skirts at a discount, which would cause him to lose $3 per defective skirt. In February, for every 20 skirts sold, 5 were defective. Cody earned $1260 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 Cody earned
= 195 u - 15 u
= 180 u
180 u = 1260
1 u = 1260 ÷ 180 = 7
Number of more skirts sold that were good than defective
= 15 u - 5 u
= 10 u
= 10 x 7
= 70
(b)
Number of defective skirts
= 5 u
= 5 x 7
= 35
Less amount earned for one defective jacket
= 13 + 3
= $16
Less amount earned because of all the defective skirts
= 35 x 16
= $560
Answer(s): (a) 70; (b) $560
