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

(a)
Amount that Ken earned
= 399 u - 36 u
= 363 u
363 u = 2904
1 u = 2904 ÷ 363 = 8
Number of more jackets sold that were good than defective
= 21 u - 9 u
= 12 u
= 12 x 8
= 96
(b)
Number of defective jackets
= 9 u
= 9 x 8
= 72
Less amount earned for one defective jacket
= 19 + 4
= $23
Less amount earned because of all the defective jackets
= 72 x 23
= $1656
Answer(s): (a) 96; (b) $1656
