For every good jacket that Andy sold, Andy earned $13. He sold defective jackets at a discount, which would cause him to lose $3 per defective jacket. In September, for every 28 jackets sold, 11 were defective. Andy earned $1128 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 Andy earned
= 221 u - 33 u
= 188 u
188 u = 1128
1 u = 1128 ÷ 188 = 6
Number of more jackets sold that were good than defective
= 17 u - 11 u
= 6 u
= 6 x 6
= 36
(b)
Number of defective jackets
= 11 u
= 11 x 6
= 66
Less amount earned for one defective jacket
= 13 + 3
= $16
Less amount earned because of all the defective jackets
= 66 x 16
= $1056
Answer(s): (a) 36; (b) $1056
