For every good windbreaker that Caden sold, Caden earned $20. He sold defective windbreakers at a discount, which would cause him to lose $3 per defective windbreaker. In September, for every 21 windbreakers sold, 8 were defective. Caden earned $2124 from the windbreakers sold.

1. How many less windbreakers sold were defective than good?
2. How much less money did he earn because of the defective windbreakers?

	Good	Defective	Total
Number	13 u	8 u
Value	+ 20	- 3
Total Value	260 u	- 24 u	$2124

(a)
Amount that Caden earned 
= 260 u - 24 u
= 236 u

236 u = 2124

1 u = 2124 ÷ 236 = 9

Number of less windbreakers sold that were defective than good
= 13 u - 8 u
= 5 u
= 5 x 9
= 45

(b)
Number of defective windbreakers
= 8 u
= 8 x 9
= 72

Less amount earned for one defective jacket
= 20 + 3
= $23

Less amount earned because of all the defective windbreakers
= 72 x 23
= $1656

Answer(s): (a) 45; (b) $1656
