For every good skirt that Bobby sold, Bobby earned $19. He sold defective skirts at a discount, which would cause him to lose $5 per defective skirt. In January, for every 22 skirts sold, 8 were defective. Bobby earned $1130 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 Bobby earned
= 266 u - 40 u
= 226 u
226 u = 1130
1 u = 1130 ÷ 226 = 5
Number of more skirts sold that were good than defective
= 14 u - 8 u
= 6 u
= 6 x 5
= 30
(b)
Number of defective skirts
= 8 u
= 8 x 5
= 40
Less amount earned for one defective jacket
= 19 + 5
= $24
Less amount earned because of all the defective skirts
= 40 x 24
= $960
Answer(s): (a) 30; (b) $960
