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

(a)
Amount that Perry earned
= 450 u - 27 u
= 423 u
423 u = 2961
1 u = 2961 ÷ 423 = 7
Number of less shirts sold that were defective than good
= 18 u - 9 u
= 9 u
= 9 x 7
= 63
(b)
Number of defective shirts
= 9 u
= 9 x 7
= 63
Less amount earned for one defective jacket
= 25 + 3
= $28
Less amount earned because of all the defective shirts
= 63 x 28
= $1764
Answer(s): (a) 63; (b) $1764
