For every good skirt that Tim sold, Tim earned $15. He sold defective skirts at a discount, which would cause him to lose $4 per defective skirt. In August, for every 26 skirts sold, 11 were defective. Tim earned $905 from the skirts sold.
- How many more skirts sold were good than defective?
- How much less money did he earn because of the defective skirts?

(a)
Amount that Tim earned
= 225 u - 44 u
= 181 u
181 u = 905
1 u = 905 ÷ 181 = 5
Number of more skirts sold that were good than defective
= 15 u - 11 u
= 4 u
= 4 x 5
= 20
(b)
Number of defective skirts
= 11 u
= 11 x 5
= 55
Less amount earned for one defective jacket
= 15 + 4
= $19
Less amount earned because of all the defective skirts
= 55 x 19
= $1045
Answer(s): (a) 20; (b) $1045
