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

(a)
Amount that Sam earned
= 238 u - 55 u
= 183 u
183 u = 915
1 u = 915 ÷ 183 = 5
Number of more shirts sold that were good than defective
= 14 u - 11 u
= 3 u
= 3 x 5
= 15
(b)
Number of defective shirts
= 11 u
= 11 x 5
= 55
Less amount earned for one defective jacket
= 17 + 5
= $22
Less amount earned because of all the defective shirts
= 55 x 22
= $1210
Answer(s): (a) 15; (b) $1210
