- How many less sweaters sold were defective than good?
- How much less money did he earn because of the defective sweaters?

(a)
Amount that Warren earned
= 306 u - 15 u
= 291 u
291 u = 1746
1 u = 1746 ÷ 291 = 6
Number of less sweaters sold that were defective than good
= 18 u - 3 u
= 15 u
= 15 x 6
= 90
(b)
Number of defective sweaters
= 3 u
= 3 x 6
= 18
Less amount earned for one defective jacket
= 17 + 5
= $22
Less amount earned because of all the defective sweaters
= 18 x 22
= $396
Answer(s): (a) 90; (b) $396
