For every good skirt that Bobby sold, Bobby earned $13. He sold defective skirts at a discount, which would cause him to lose $2 per defective skirt. In April, for every 28 skirts sold, 3 were defective. Bobby earned $957 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 Bobby earned
= 325 u - 6 u
= 319 u
319 u = 957
1 u = 957 ÷ 319 = 3
Number of less skirts sold that were defective than good
= 25 u - 3 u
= 22 u
= 22 x 3
= 66
(b)
Number of defective skirts
= 3 u
= 3 x 3
= 9
Less amount earned for one defective jacket
= 13 + 2
= $15
Less amount earned because of all the defective skirts
= 9 x 15
= $135
Answer(s): (a) 66; (b) $135
