For every good coat that Justin sold, Justin earned $24. He sold defective coats at a discount, which would cause him to lose $2 per defective coat. In January, for every 29 coats sold, 5 were defective. Justin earned $5094 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 Justin earned
= 576 u - 10 u
= 566 u
566 u = 5094
1 u = 5094 ÷ 566 = 9
Number of less coats sold that were defective than good
= 24 u - 5 u
= 19 u
= 19 x 9
= 171
(b)
Number of defective coats
= 5 u
= 5 x 9
= 45
Less amount earned for one defective jacket
= 24 + 2
= $26
Less amount earned because of all the defective coats
= 45 x 26
= $1170
Answer(s): (a) 171; (b) $1170
