For every good jumpsuit that Elijah sold, Elijah earned $20. He sold defective jumpsuits at a discount, which would cause him to lose $4 per defective jumpsuit. In August, for every 30 jumpsuits sold, 7 were defective. Elijah earned $3024 from the jumpsuits sold.
- How many more jumpsuits sold were good than defective?
- How much less money did he earn because of the defective jumpsuits?

(a)
Amount that Elijah earned
= 460 u - 28 u
= 432 u
432 u = 3024
1 u = 3024 ÷ 432 = 7
Number of more jumpsuits sold that were good than defective
= 23 u - 7 u
= 16 u
= 16 x 7
= 112
(b)
Number of defective jumpsuits
= 7 u
= 7 x 7
= 49
Less amount earned for one defective jacket
= 20 + 4
= $24
Less amount earned because of all the defective jumpsuits
= 49 x 24
= $1176
Answer(s): (a) 112; (b) $1176
