For every good jumpsuit that Tom sold, Tom earned $24. He sold defective jumpsuits at a discount, which would cause him to lose $4 per defective jumpsuit. In October, for every 21 jumpsuits sold, 7 were defective. Tom earned $2772 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 Tom earned
= 336 u - 28 u
= 308 u
308 u = 2772
1 u = 2772 ÷ 308 = 9
Number of more jumpsuits sold that were good than defective
= 14 u - 7 u
= 7 u
= 7 x 9
= 63
(b)
Number of defective jumpsuits
= 7 u
= 7 x 9
= 63
Less amount earned for one defective jacket
= 24 + 4
= $28
Less amount earned because of all the defective jumpsuits
= 63 x 28
= $1764
Answer(s): (a) 63; (b) $1764
