For every good coat that Jeremy sold, Jeremy earned $23. He sold defective coats at a discount, which would cause him to lose $5 per defective coat. In April, for every 27 coats sold, 7 were defective. Jeremy earned $3400 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 Jeremy earned
= 460 u - 35 u
= 425 u
425 u = 3400
1 u = 3400 ÷ 425 = 8
Number of less coats sold that were defective than good
= 20 u - 7 u
= 13 u
= 13 x 8
= 104
(b)
Number of defective coats
= 7 u
= 7 x 8
= 56
Less amount earned for one defective jacket
= 23 + 5
= $28
Less amount earned because of all the defective coats
= 56 x 28
= $1568
Answer(s): (a) 104; (b) $1568
