For every good blazer that Luke sold, Luke earned $15. He sold defective blazers at a discount, which would cause him to lose $3 per defective blazer. In August, for every 27 blazers sold, 11 were defective. Luke earned $1242 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 Luke earned
= 240 u - 33 u
= 207 u
207 u = 1242
1 u = 1242 ÷ 207 = 6
Number of less blazers sold that were defective than good
= 16 u - 11 u
= 5 u
= 5 x 6
= 30
(b)
Number of defective blazers
= 11 u
= 11 x 6
= 66
Less amount earned for one defective jacket
= 15 + 3
= $18
Less amount earned because of all the defective blazers
= 66 x 18
= $1188
Answer(s): (a) 30; (b) $1188
