Question

Jane, Bob, and Eric have a total of 

$100

 in their wallets. Eric has 

4

 times what Bob has. Jane has 

$8

 less than Bob. How much does each have?

Answer 1

x = amount Bob has

4x = amount Eric has

x - 8 = amount Jane has

x + 4x + (x - 8) = 100

6x = 108

x = 18

4x = 4(18) = 72

x - 8 = 18 - 8 = 10

Bob has $18, Eric has $72, Jane has $10.
