For every good coat that Harry sold, Harry earned $25. He sold defective coats at a discount, which would cause him to lose $5 per defective coat. In October, for every 24 coats sold, 9 were defective. Harry earned $2310 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 Harry earned
= 375 u - 45 u
= 330 u
330 u = 2310
1 u = 2310 ÷ 330 = 7
Number of more coats sold that were good than defective
= 15 u - 9 u
= 6 u
= 6 x 7
= 42
(b)
Number of defective coats
= 9 u
= 9 x 7
= 63
Less amount earned for one defective jacket
= 25 + 5
= $30
Less amount earned because of all the defective coats
= 63 x 30
= $1890
Answer(s): (a) 42; (b) $1890
