For every good blazer that Rael sold, Rael earned $12. He sold defective blazers at a discount, which would cause him to lose $2 per defective blazer. In March, for every 20 blazers sold, 7 were defective. Rael earned $1278 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 Rael earned
= 156 u - 14 u
= 142 u
142 u = 1278
1 u = 1278 ÷ 142 = 9
Number of more blazers sold that were good than defective
= 13 u - 7 u
= 6 u
= 6 x 9
= 54
(b)
Number of defective blazers
= 7 u
= 7 x 9
= 63
Less amount earned for one defective jacket
= 12 + 2
= $14
Less amount earned because of all the defective blazers
= 63 x 14
= $882
Answer(s): (a) 54; (b) $882
