For every good vest that Lee sold, Lee earned $15. He sold defective vests at a discount, which would cause him to lose $5 per defective vest. In April, for every 27 vests sold, 6 were defective. Lee earned $1140 from the vests sold.
- How many more vests sold were good than defective?
- How much less money did he earn because of the defective vests?

(a)
Amount that Lee earned
= 315 u - 30 u
= 285 u
285 u = 1140
1 u = 1140 ÷ 285 = 4
Number of more vests sold that were good than defective
= 21 u - 6 u
= 15 u
= 15 x 4
= 60
(b)
Number of defective vests
= 6 u
= 6 x 4
= 24
Less amount earned for one defective jacket
= 15 + 5
= $20
Less amount earned because of all the defective vests
= 24 x 20
= $480
Answer(s): (a) 60; (b) $480
