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

(a)
Amount that Billy earned
= 368 u - 36 u
= 332 u
332 u = 2988
1 u = 2988 ÷ 332 = 9
Number of less jackets sold that were defective than good
= 16 u - 9 u
= 7 u
= 7 x 9
= 63
(b)
Number of defective jackets
= 9 u
= 9 x 9
= 81
Less amount earned for one defective jacket
= 23 + 4
= $27
Less amount earned because of all the defective jackets
= 81 x 27
= $2187
Answer(s): (a) 63; (b) $2187
