Question

1. The ratio of Carlos’s money to Ava’s money to Zach’s money is 4:5:9. If Zach has $168 more than Ava,

   1. How much money does Ava have?

   2. How much money will Zack have left if he spends 1/3 of it? 

Answer 1

A/Z = 5/9

Z = A + 168

A/(A+ 168) = 5/9

9A = 5A + 5* 168

9A-5A= 5*168

4A = 5*168

A= 5*168/4

A = 5*42

A = 210 ($ )
