For every good sweater that Dylan sold, Dylan earned $22. He sold defective sweaters at a discount, which would cause him to lose $3 per defective sweater. In May, for every 20 sweaters sold, 7 were defective. Dylan earned $530 from the sweaters sold.
- How many less sweaters sold were defective than good?
- How much less money did he earn because of the defective sweaters?

(a)
Amount that Dylan earned
= 286 u - 21 u
= 265 u
265 u = 530
1 u = 530 ÷ 265 = 2
Number of less sweaters sold that were defective than good
= 13 u - 7 u
= 6 u
= 6 x 2
= 12
(b)
Number of defective sweaters
= 7 u
= 7 x 2
= 14
Less amount earned for one defective jacket
= 22 + 3
= $25
Less amount earned because of all the defective sweaters
= 14 x 25
= $350
Answer(s): (a) 12; (b) $350
