For every good coat that Simon sold, Simon earned $20. He sold defective coats at a discount, which would cause him to lose $5 per defective coat. In August, for every 27 coats sold, 9 were defective. Simon earned $2205 from the coats sold.
- How many more coats sold were good than defective?
- How much less money did he earn because of the defective coats?

(a)
Amount that Simon earned
= 360 u - 45 u
= 315 u
315 u = 2205
1 u = 2205 ÷ 315 = 7
Number of more coats sold that were good than defective
= 18 u - 9 u
= 9 u
= 9 x 7
= 63
(b)
Number of defective coats
= 9 u
= 9 x 7
= 63
Less amount earned for one defective jacket
= 20 + 5
= $25
Less amount earned because of all the defective coats
= 63 x 25
= $1575
Answer(s): (a) 63; (b) $1575
