For every good windbreaker that Xavier sold, Xavier earned $21. He sold defective windbreakers at a discount, which would cause him to lose $4 per defective windbreaker. In August, for every 29 windbreakers sold, 11 were defective. Xavier earned $1002 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	18 u	11 u
Value	+ 21	- 4
Total Value	378 u	- 44 u	$1002

(a)
Amount that Xavier earned 
= 378 u - 44 u
= 334 u

334 u = 1002

1 u = 1002 ÷ 334 = 3

Number of less windbreakers sold that were defective than good
= 18 u - 11 u
= 7 u
= 7 x 3
= 21

(b)
Number of defective windbreakers
= 11 u
= 11 x 3
= 33

Less amount earned for one defective jacket
= 21 + 4
= $25

Less amount earned because of all the defective windbreakers
= 33 x 25
= $825

Answer(s): (a) 21; (b) $825
