For every good jacket that Brandon sold, Brandon earned $18. He sold defective jackets at a discount, which would cause him to lose $5 per defective jacket. In April, for every 30 jackets sold, 3 were defective. Brandon earned $1413 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 Brandon earned
= 486 u - 15 u
= 471 u
471 u = 1413
1 u = 1413 ÷ 471 = 3
Number of less jackets sold that were defective than good
= 27 u - 3 u
= 24 u
= 24 x 3
= 72
(b)
Number of defective jackets
= 3 u
= 3 x 3
= 9
Less amount earned for one defective jacket
= 18 + 5
= $23
Less amount earned because of all the defective jackets
= 9 x 23
= $207
Answer(s): (a) 72; (b) $207
