For every good coat that Riordan sold, Riordan earned $24. He sold defective coats at a discount, which would cause him to lose $3 per defective coat. In June, for every 24 coats sold, 8 were defective. Riordan earned $1440 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 Riordan earned
= 384 u - 24 u
= 360 u
360 u = 1440
1 u = 1440 ÷ 360 = 4
Number of more coats sold that were good than defective
= 16 u - 8 u
= 8 u
= 8 x 4
= 32
(b)
Number of defective coats
= 8 u
= 8 x 4
= 32
Less amount earned for one defective jacket
= 24 + 3
= $27
Less amount earned because of all the defective coats
= 32 x 27
= $864
Answer(s): (a) 32; (b) $864
