For every good jacket that Riordan sold, Riordan earned $25. He sold defective jackets at a discount, which would cause him to lose $3 per defective jacket. In August, for every 26 jackets sold, 11 were defective. Riordan earned $2736 from the jackets sold.
- How many more jackets sold were good than defective?
- How much less money did he earn because of the defective jackets?

(a)
Amount that Riordan earned
= 375 u - 33 u
= 342 u
342 u = 2736
1 u = 2736 ÷ 342 = 8
Number of more jackets sold that were good than defective
= 15 u - 11 u
= 4 u
= 4 x 8
= 32
(b)
Number of defective jackets
= 11 u
= 11 x 8
= 88
Less amount earned for one defective jacket
= 25 + 3
= $28
Less amount earned because of all the defective jackets
= 88 x 28
= $2464
Answer(s): (a) 32; (b) $2464
