For every good coat that John sold, John earned $14. He sold defective coats at a discount, which would cause him to lose $2 per defective coat. In June, for every 22 coats sold, 8 were defective. John earned $1080 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 John earned
= 196 u - 16 u
= 180 u
180 u = 1080
1 u = 1080 ÷ 180 = 6
Number of less coats sold that were defective than good
= 14 u - 8 u
= 6 u
= 6 x 6
= 36
(b)
Number of defective coats
= 8 u
= 8 x 6
= 48
Less amount earned for one defective jacket
= 14 + 2
= $16
Less amount earned because of all the defective coats
= 48 x 16
= $768
Answer(s): (a) 36; (b) $768
