For every good blazer that Tommy sold, Tommy earned $15. He sold defective blazers at a discount, which would cause him to lose $4 per defective blazer. In February, for every 30 blazers sold, 11 were defective. Tommy earned $1446 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 Tommy earned
= 285 u - 44 u
= 241 u
241 u = 1446
1 u = 1446 ÷ 241 = 6
Number of more blazers sold that were good than defective
= 19 u - 11 u
= 8 u
= 8 x 6
= 48
(b)
Number of defective blazers
= 11 u
= 11 x 6
= 66
Less amount earned for one defective jacket
= 15 + 4
= $19
Less amount earned because of all the defective blazers
= 66 x 19
= $1254
Answer(s): (a) 48; (b) $1254
