For every good vest that Simon sold, Simon earned $18. He sold defective vests at a discount, which would cause him to lose $4 per defective vest. In June, for every 22 vests sold, 10 were defective. Simon earned $1056 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
= 216 u - 40 u
= 176 u
176 u = 1056
1 u = 1056 ÷ 176 = 6
Number of more vests sold that were good than defective
= 12 u - 10 u
= 2 u
= 2 x 6
= 12
(b)
Number of defective vests
= 10 u
= 10 x 6
= 60
Less amount earned for one defective jacket
= 18 + 4
= $22
Less amount earned because of all the defective vests
= 60 x 22
= $1320
Answer(s): (a) 12; (b) $1320
