For every good blazer that Billy sold, Billy earned $15. He sold defective blazers at a discount, which would cause him to lose $5 per defective blazer. In June, for every 28 blazers sold, 11 were defective. Billy earned $1600 from the blazers sold.
- How many less blazers sold were defective than good?
- How much less money did he earn because of the defective blazers?

(a)
Amount that Billy earned
= 255 u - 55 u
= 200 u
200 u = 1600
1 u = 1600 ÷ 200 = 8
Number of less blazers sold that were defective than good
= 17 u - 11 u
= 6 u
= 6 x 8
= 48
(b)
Number of defective blazers
= 11 u
= 11 x 8
= 88
Less amount earned for one defective jacket
= 15 + 5
= $20
Less amount earned because of all the defective blazers
= 88 x 20
= $1760
Answer(s): (a) 48; (b) $1760
