For every good coat that Gabriel sold, Gabriel earned $25. He sold defective coats at a discount, which would cause him to lose $4 per defective coat. In October, for every 29 coats sold, 3 were defective. Gabriel earned $3828 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 Gabriel earned
= 650 u - 12 u
= 638 u
638 u = 3828
1 u = 3828 ÷ 638 = 6
Number of less coats sold that were defective than good
= 26 u - 3 u
= 23 u
= 23 x 6
= 138
(b)
Number of defective coats
= 3 u
= 3 x 6
= 18
Less amount earned for one defective jacket
= 25 + 4
= $29
Less amount earned because of all the defective coats
= 18 x 29
= $522
Answer(s): (a) 138; (b) $522
