For every good skirt that Bryan sold, Bryan earned $22. He sold defective skirts at a discount, which would cause him to lose $3 per defective skirt. In January, for every 20 skirts sold, 4 were defective. Bryan earned $1360 from the skirts sold.
- How many less skirts sold were defective than good?
- How much less money did he earn because of the defective skirts?

(a)
Amount that Bryan earned
= 352 u - 12 u
= 340 u
340 u = 1360
1 u = 1360 ÷ 340 = 4
Number of less skirts sold that were defective than good
= 16 u - 4 u
= 12 u
= 12 x 4
= 48
(b)
Number of defective skirts
= 4 u
= 4 x 4
= 16
Less amount earned for one defective jacket
= 22 + 3
= $25
Less amount earned because of all the defective skirts
= 16 x 25
= $400
Answer(s): (a) 48; (b) $400
