For every good dress that Japheth sold, Japheth earned $20. He sold defective dresses at a discount, which would cause him to lose $2 per defective dress. In October, for every 21 dresses sold, 7 were defective. Japheth earned $1862 from the dresses sold.
- How many more dresses sold were good than defective?
- How much less money did he earn because of the defective dresses?

(a)
Amount that Japheth earned
= 280 u - 14 u
= 266 u
266 u = 1862
1 u = 1862 ÷ 266 = 7
Number of more dresses sold that were good than defective
= 14 u - 7 u
= 7 u
= 7 x 7
= 49
(b)
Number of defective dresses
= 7 u
= 7 x 7
= 49
Less amount earned for one defective jacket
= 20 + 2
= $22
Less amount earned because of all the defective dresses
= 49 x 22
= $1078
Answer(s): (a) 49; (b) $1078
