For every good blazer that Valen sold, Valen earned $23. He sold defective blazers at a discount, which would cause him to lose $5 per defective blazer. In July, for every 30 blazers sold, 5 were defective. Valen earned $3850 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 Valen earned
= 575 u - 25 u
= 550 u
550 u = 3850
1 u = 3850 ÷ 550 = 7
Number of more blazers sold that were good than defective
= 25 u - 5 u
= 20 u
= 20 x 7
= 140
(b)
Number of defective blazers
= 5 u
= 5 x 7
= 35
Less amount earned for one defective jacket
= 23 + 5
= $28
Less amount earned because of all the defective blazers
= 35 x 28
= $980
Answer(s): (a) 140; (b) $980
