For every good skirt that Warren sold, Warren earned $12. He sold defective skirts at a discount, which would cause him to lose $5 per defective skirt. In November, for every 26 skirts sold, 3 were defective. Warren earned $1827 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 Warren earned
= 276 u - 15 u
= 261 u
261 u = 1827
1 u = 1827 ÷ 261 = 7
Number of less skirts sold that were defective than good
= 23 u - 3 u
= 20 u
= 20 x 7
= 140
(b)
Number of defective skirts
= 3 u
= 3 x 7
= 21
Less amount earned for one defective jacket
= 12 + 5
= $17
Less amount earned because of all the defective skirts
= 21 x 17
= $357
Answer(s): (a) 140; (b) $357
