For every good shirt that Albert sold, Albert earned $23. He sold defective shirts at a discount, which would cause him to lose $3 per defective shirt. In April, for every 27 shirts sold, 12 were defective. Albert earned $2163 from the shirts sold.
- How many more shirts sold were good than defective?
- How much less money did he earn because of the defective shirts?

(a)
Amount that Albert earned
= 345 u - 36 u
= 309 u
309 u = 2163
1 u = 2163 ÷ 309 = 7
Number of more shirts sold that were good than defective
= 15 u - 12 u
= 3 u
= 3 x 7
= 21
(b)
Number of defective shirts
= 12 u
= 12 x 7
= 84
Less amount earned for one defective jacket
= 23 + 3
= $26
Less amount earned because of all the defective shirts
= 84 x 26
= $2184
Answer(s): (a) 21; (b) $2184
