For every good dress that Cody sold, Cody earned $17. He sold defective dresses at a discount, which would cause him to lose $5 per defective dress. In February, for every 30 dresses sold, 5 were defective. Cody earned $2000 from the dresses sold.
- How many less dresses sold were defective than good?
- How much less money did he earn because of the defective dresses?

(a)
Amount that Cody earned
= 425 u - 25 u
= 400 u
400 u = 2000
1 u = 2000 ÷ 400 = 5
Number of less dresses sold that were defective than good
= 25 u - 5 u
= 20 u
= 20 x 5
= 100
(b)
Number of defective dresses
= 5 u
= 5 x 5
= 25
Less amount earned for one defective jacket
= 17 + 5
= $22
Less amount earned because of all the defective dresses
= 25 x 22
= $550
Answer(s): (a) 100; (b) $550
