For every good windbreaker that Paul sold, Paul earned $18. He sold defective windbreakers at a discount, which would cause him to lose $5 per defective windbreaker. In April, for every 27 windbreakers sold, 7 were defective. Paul earned $1950 from the windbreakers sold.

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

	Good	Defective	Total
Number	20 u	7 u
Value	+ 18	- 5
Total Value	360 u	- 35 u	$1950

(a)
Amount that Paul earned 
= 360 u - 35 u
= 325 u

325 u = 1950

1 u = 1950 ÷ 325 = 6

Number of more windbreakers sold that were good than defective
= 20 u - 7 u
= 13 u
= 13 x 6
= 78

(b)
Number of defective windbreakers
= 7 u
= 7 x 6
= 42

Less amount earned for one defective jacket
= 18 + 5
= $23

Less amount earned because of all the defective windbreakers
= 42 x 23
= $966

Answer(s): (a) 78; (b) $966
