For every good jumpsuit that Jenson sold, Jenson earned $19. He sold defective jumpsuits at a discount, which would cause him to lose $3 per defective jumpsuit. In October, for every 28 jumpsuits sold, 4 were defective. Jenson earned $3996 from the jumpsuits sold.

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

	Good	Defective	Total
Number	24 u	4 u
Value	+ 19	- 3
Total Value	456 u	- 12 u	$3996

(a)
Amount that Jenson earned 
= 456 u - 12 u
= 444 u

444 u = 3996

1 u = 3996 ÷ 444 = 9

Number of less jumpsuits sold that were defective than good
= 24 u - 4 u
= 20 u
= 20 x 9
= 180

(b)
Number of defective jumpsuits
= 4 u
= 4 x 9
= 36

Less amount earned for one defective jacket
= 19 + 3
= $22

Less amount earned because of all the defective jumpsuits
= 36 x 22
= $792

Answer(s): (a) 180; (b) $792
