- How many more vests sold were good than defective?
- How much less money did he earn because of the defective vests?

(a)
Amount that Glen earned
= 528 u - 12 u
= 516 u
516 u = 3612
1 u = 3612 ÷ 516 = 7
Number of more vests sold that were good than defective
= 24 u - 3 u
= 21 u
= 21 x 7
= 147
(b)
Number of defective vests
= 3 u
= 3 x 7
= 21
Less amount earned for one defective jacket
= 22 + 4
= $26
Less amount earned because of all the defective vests
= 21 x 26
= $546
Answer(s): (a) 147; (b) $546
