For every good jacket that Rael sold, Rael earned $22. He sold defective jackets at a discount, which would cause him to lose $3 per defective jacket. In March, for every 21 jackets sold, 3 were defective. Rael earned $1161 from the jackets sold.
- How many less jackets sold were defective than good?
- How much less money did he earn because of the defective jackets?

(a)
Amount that Rael earned
= 396 u - 9 u
= 387 u
387 u = 1161
1 u = 1161 ÷ 387 = 3
Number of less jackets sold that were defective than good
= 18 u - 3 u
= 15 u
= 15 x 3
= 45
(b)
Number of defective jackets
= 3 u
= 3 x 3
= 9
Less amount earned for one defective jacket
= 22 + 3
= $25
Less amount earned because of all the defective jackets
= 9 x 25
= $225
Answer(s): (a) 45; (b) $225
