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

(a)
Amount that Oscar earned
= 272 u - 44 u
= 228 u
228 u = 456
1 u = 456 ÷ 228 = 2
Number of less shirts sold that were defective than good
= 16 u - 11 u
= 5 u
= 5 x 2
= 10
(b)
Number of defective shirts
= 11 u
= 11 x 2
= 22
Less amount earned for one defective jacket
= 17 + 4
= $21
Less amount earned because of all the defective shirts
= 22 x 21
= $462
Answer(s): (a) 10; (b) $462
