For every good coat that Cody sold, Cody earned $21. He sold defective coats at a discount, which would cause him to lose $4 per defective coat. In March, for every 28 coats sold, 3 were defective. Cody earned $1026 from the coats sold.
- How many less coats sold were defective than good?
- How much less money did he earn because of the defective coats?

(a)
Amount that Cody earned
= 525 u - 12 u
= 513 u
513 u = 1026
1 u = 1026 ÷ 513 = 2
Number of less coats sold that were defective than good
= 25 u - 3 u
= 22 u
= 22 x 2
= 44
(b)
Number of defective coats
= 3 u
= 3 x 2
= 6
Less amount earned for one defective jacket
= 21 + 4
= $25
Less amount earned because of all the defective coats
= 6 x 25
= $150
Answer(s): (a) 44; (b) $150
