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

(a)
Amount that Pierre earned
= 456 u - 21 u
= 435 u
435 u = 3915
1 u = 3915 ÷ 435 = 9
Number of less coats sold that were defective than good
= 19 u - 7 u
= 12 u
= 12 x 9
= 108
(b)
Number of defective coats
= 7 u
= 7 x 9
= 63
Less amount earned for one defective jacket
= 24 + 3
= $27
Less amount earned because of all the defective coats
= 63 x 27
= $1701
Answer(s): (a) 108; (b) $1701
