For every good coat that Brandon sold, Brandon earned $15. He sold defective coats at a discount, which would cause him to lose $5 per defective coat. In February, for every 23 coats sold, 5 were defective. Brandon earned $1225 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 Brandon earned
= 270 u - 25 u
= 245 u
245 u = 1225
1 u = 1225 ÷ 245 = 5
Number of less coats sold that were defective than good
= 18 u - 5 u
= 13 u
= 13 x 5
= 65
(b)
Number of defective coats
= 5 u
= 5 x 5
= 25
Less amount earned for one defective jacket
= 15 + 5
= $20
Less amount earned because of all the defective coats
= 25 x 20
= $500
Answer(s): (a) 65; (b) $500
