For every good jumpsuit that Justin sold, Justin earned $24. He sold defective jumpsuits at a discount, which would cause him to lose $5 per defective jumpsuit. In October, for every 30 jumpsuits sold, 4 were defective. Justin earned $3020 from the jumpsuits sold.

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

	Good	Defective	Total
Number	26 u	4 u
Value	+ 24	- 5
Total Value	624 u	- 20 u	$3020

(a)
Amount that Justin earned 
= 624 u - 20 u
= 604 u

604 u = 3020

1 u = 3020 ÷ 604 = 5

Number of more jumpsuits sold that were good than defective
= 26 u - 4 u
= 22 u
= 22 x 5
= 110

(b)
Number of defective jumpsuits
= 4 u
= 4 x 5
= 20

Less amount earned for one defective jacket
= 24 + 5
= $29

Less amount earned because of all the defective jumpsuits
= 20 x 29
= $580

Answer(s): (a) 110; (b) $580
