For every good coat that Luis sold, Luis earned $16. He sold defective coats at a discount, which would cause him to lose $4 per defective coat. In January, for every 25 coats sold, 5 were defective. Luis earned $1500 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 Luis earned
= 320 u - 20 u
= 300 u
300 u = 1500
1 u = 1500 ÷ 300 = 5
Number of less coats sold that were defective than good
= 20 u - 5 u
= 15 u
= 15 x 5
= 75
(b)
Number of defective coats
= 5 u
= 5 x 5
= 25
Less amount earned for one defective jacket
= 16 + 4
= $20
Less amount earned because of all the defective coats
= 25 x 20
= $500
Answer(s): (a) 75; (b) $500
