For every good skirt that Carl sold, Carl earned $16. He sold defective skirts at a discount, which would cause him to lose $3 per defective skirt. In September, for every 28 skirts sold, 9 were defective. Carl earned $554 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 Carl earned
= 304 u - 27 u
= 277 u
277 u = 554
1 u = 554 ÷ 277 = 2
Number of less skirts sold that were defective than good
= 19 u - 9 u
= 10 u
= 10 x 2
= 20
(b)
Number of defective skirts
= 9 u
= 9 x 2
= 18
Less amount earned for one defective jacket
= 16 + 3
= $19
Less amount earned because of all the defective skirts
= 18 x 19
= $342
Answer(s): (a) 20; (b) $342
