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

(a)
Amount that Sam earned
= 380 u - 18 u
= 362 u
362 u = 3258
1 u = 3258 ÷ 362 = 9
Number of more coats sold that were good than defective
= 20 u - 6 u
= 14 u
= 14 x 9
= 126
(b)
Number of defective coats
= 6 u
= 6 x 9
= 54
Less amount earned for one defective jacket
= 19 + 3
= $22
Less amount earned because of all the defective coats
= 54 x 22
= $1188
Answer(s): (a) 126; (b) $1188
