For every good vest that Caden sold, Caden earned $24. He sold defective vests at a discount, which would cause him to lose $4 per defective vest. In November, for every 28 vests sold, 5 were defective. Caden earned $3192 from the vests sold.
- How many less vests sold were defective than good?
- How much less money did he earn because of the defective vests?

(a)
Amount that Caden earned
= 552 u - 20 u
= 532 u
532 u = 3192
1 u = 3192 ÷ 532 = 6
Number of less vests sold that were defective than good
= 23 u - 5 u
= 18 u
= 18 x 6
= 108
(b)
Number of defective vests
= 5 u
= 5 x 6
= 30
Less amount earned for one defective jacket
= 24 + 4
= $28
Less amount earned because of all the defective vests
= 30 x 28
= $840
Answer(s): (a) 108; (b) $840
