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

(a)
Amount that Julian earned
= 300 u - 18 u
= 282 u
282 u = 2538
1 u = 2538 ÷ 282 = 9
Number of less jackets sold that were defective than good
= 15 u - 9 u
= 6 u
= 6 x 9
= 54
(b)
Number of defective jackets
= 9 u
= 9 x 9
= 81
Less amount earned for one defective jacket
= 20 + 2
= $22
Less amount earned because of all the defective jackets
= 81 x 22
= $1782
Answer(s): (a) 54; (b) $1782
