For every good blazer that Oliver sold, Oliver earned $15. He sold defective blazers at a discount, which would cause him to lose $5 per defective blazer. In March, for every 22 blazers sold, 7 were defective. Oliver earned $1710 from the blazers sold.
- How many more blazers sold were good than defective?
- How much less money did he earn because of the defective blazers?

(a)
Amount that Oliver earned
= 225 u - 35 u
= 190 u
190 u = 1710
1 u = 1710 ÷ 190 = 9
Number of more blazers sold that were good than defective
= 15 u - 7 u
= 8 u
= 8 x 9
= 72
(b)
Number of defective blazers
= 7 u
= 7 x 9
= 63
Less amount earned for one defective jacket
= 15 + 5
= $20
Less amount earned because of all the defective blazers
= 63 x 20
= $1260
Answer(s): (a) 72; (b) $1260
