For every good jumpsuit that Elijah sold, Elijah earned $12. He sold defective jumpsuits at a discount, which would cause him to lose $4 per defective jumpsuit. In February, for every 29 jumpsuits sold, 11 were defective. Elijah earned $1204 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	18 u	11 u
Value	+ 12	- 4
Total Value	216 u	- 44 u	$1204

(a)
Amount that Elijah earned 
= 216 u - 44 u
= 172 u

172 u = 1204

1 u = 1204 ÷ 172 = 7

Number of less jumpsuits sold that were defective than good
= 18 u - 11 u
= 7 u
= 7 x 7
= 49

(b)
Number of defective jumpsuits
= 11 u
= 11 x 7
= 77

Less amount earned for one defective jacket
= 12 + 4
= $16

Less amount earned because of all the defective jumpsuits
= 77 x 16
= $1232

Answer(s): (a) 49; (b) $1232
