For every good vest that Japheth sold, Japheth earned $20. He sold defective vests at a discount, which would cause him to lose $2 per defective vest. In February, for every 23 vests sold, 4 were defective. Japheth earned $1116 from the vests sold.
- How many less vests sold were defective than good?
- How much less money did he earn because of the defective vests?

(a)
Amount that Japheth earned
= 380 u - 8 u
= 372 u
372 u = 1116
1 u = 1116 ÷ 372 = 3
Number of less vests sold that were defective than good
= 19 u - 4 u
= 15 u
= 15 x 3
= 45
(b)
Number of defective vests
= 4 u
= 4 x 3
= 12
Less amount earned for one defective jacket
= 20 + 2
= $22
Less amount earned because of all the defective vests
= 12 x 22
= $264
Answer(s): (a) 45; (b) $264
