For every good vest that Simon sold, Simon earned $17. He sold defective vests at a discount, which would cause him to lose $3 per defective vest. In April, for every 24 vests sold, 5 were defective. Simon earned $924 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 Simon earned
= 323 u - 15 u
= 308 u
308 u = 924
1 u = 924 ÷ 308 = 3
Number of more vests sold that were good than defective
= 19 u - 5 u
= 14 u
= 14 x 3
= 42
(b)
Number of defective vests
= 5 u
= 5 x 3
= 15
Less amount earned for one defective jacket
= 17 + 3
= $20
Less amount earned because of all the defective vests
= 15 x 20
= $300
Answer(s): (a) 42; (b) $300
