For every good coat that Caden sold, Caden earned $21. He sold defective coats at a discount, which would cause him to lose $2 per defective coat. In November, for every 20 coats sold, 9 were defective. Caden earned $1065 from the coats sold.
- How many more coats sold were good than defective?
- How much less money did he earn because of the defective coats?

(a)
Amount that Caden earned
= 231 u - 18 u
= 213 u
213 u = 1065
1 u = 1065 ÷ 213 = 5
Number of more coats sold that were good than defective
= 11 u - 9 u
= 2 u
= 2 x 5
= 10
(b)
Number of defective coats
= 9 u
= 9 x 5
= 45
Less amount earned for one defective jacket
= 21 + 2
= $23
Less amount earned because of all the defective coats
= 45 x 23
= $1035
Answer(s): (a) 10; (b) $1035
