For every good jumpsuit that Perry sold, Perry earned $21. He sold defective jumpsuits at a discount, which would cause him to lose $3 per defective jumpsuit. In May, for every 21 jumpsuits sold, 8 were defective. Perry earned $1992 from the jumpsuits sold.
- How many less jumpsuits sold were defective than good?
- How much less money did he earn because of the defective jumpsuits?

(a)
Amount that Perry earned
= 273 u - 24 u
= 249 u
249 u = 1992
1 u = 1992 ÷ 249 = 8
Number of less jumpsuits sold that were defective than good
= 13 u - 8 u
= 5 u
= 5 x 8
= 40
(b)
Number of defective jumpsuits
= 8 u
= 8 x 8
= 64
Less amount earned for one defective jacket
= 21 + 3
= $24
Less amount earned because of all the defective jumpsuits
= 64 x 24
= $1536
Answer(s): (a) 40; (b) $1536
