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

(a)
Amount that Bobby earned
= 308 u - 20 u
= 288 u
288 u = 1152
1 u = 1152 ÷ 288 = 4
Number of more dresses sold that were good than defective
= 22 u - 4 u
= 18 u
= 18 x 4
= 72
(b)
Number of defective dresses
= 4 u
= 4 x 4
= 16
Less amount earned for one defective jacket
= 14 + 5
= $19
Less amount earned because of all the defective dresses
= 16 x 19
= $304
Answer(s): (a) 72; (b) $304
