- How many less jackets sold were defective than good?
- How much less money did he earn because of the defective jackets?

(a)
Amount that Sam earned
= 378 u - 21 u
= 357 u
357 u = 2142
1 u = 2142 ÷ 357 = 6
Number of less jackets sold that were defective than good
= 18 u - 7 u
= 11 u
= 11 x 6
= 66
(b)
Number of defective jackets
= 7 u
= 7 x 6
= 42
Less amount earned for one defective jacket
= 21 + 3
= $24
Less amount earned because of all the defective jackets
= 42 x 24
= $1008
Answer(s): (a) 66; (b) $1008
