For every good shirt that Will sold, Will earned $15. He sold defective shirts at a discount, which would cause him to lose $4 per defective shirt. In February, for every 22 shirts sold, 10 were defective. Will earned $1400 from the shirts sold.
- How many less shirts sold were defective than good?
- How much less money did he earn because of the defective shirts?

(a)
Amount that Will earned
= 180 u - 40 u
= 140 u
140 u = 1400
1 u = 1400 ÷ 140 = 10
Number of less shirts sold that were defective than good
= 12 u - 10 u
= 2 u
= 2 x 10
= 20
(b)
Number of defective shirts
= 10 u
= 10 x 10
= 100
Less amount earned for one defective jacket
= 15 + 4
= $19
Less amount earned because of all the defective shirts
= 100 x 19
= $1900
Answer(s): (a) 20; (b) $1900
