For every good shirt that Elijah sold, Elijah earned $18. He sold defective shirts at a discount, which would cause him to lose $4 per defective shirt. In July, for every 26 shirts sold, 4 were defective. Elijah earned $1900 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 Elijah earned
= 396 u - 16 u
= 380 u
380 u = 1900
1 u = 1900 ÷ 380 = 5
Number of more shirts sold that were good than defective
= 22 u - 4 u
= 18 u
= 18 x 5
= 90
(b)
Number of defective shirts
= 4 u
= 4 x 5
= 20
Less amount earned for one defective jacket
= 18 + 4
= $22
Less amount earned because of all the defective shirts
= 20 x 22
= $440
Answer(s): (a) 90; (b) $440
