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

(a)
Amount that Seth earned
= 336 u - 18 u
= 318 u
318 u = 1908
1 u = 1908 ÷ 318 = 6
Number of more dresses sold that were good than defective
= 16 u - 6 u
= 10 u
= 10 x 6
= 60
(b)
Number of defective dresses
= 6 u
= 6 x 6
= 36
Less amount earned for one defective jacket
= 21 + 3
= $24
Less amount earned because of all the defective dresses
= 36 x 24
= $864
Answer(s): (a) 60; (b) $864
