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

(a)
Amount that Pierre earned
= 228 u - 45 u
= 183 u
183 u = 549
1 u = 549 ÷ 183 = 3
Number of more jackets sold that were good than defective
= 12 u - 9 u
= 3 u
= 3 x 3
= 9
(b)
Number of defective jackets
= 9 u
= 9 x 3
= 27
Less amount earned for one defective jacket
= 19 + 5
= $24
Less amount earned because of all the defective jackets
= 27 x 24
= $648
Answer(s): (a) 9; (b) $648
