Jenny, Ali and Eric have a total of $97 in their wallets. Ali has $5 more than Jenny. Eric has 2 times what Jenny has. How much does each have?

J + a + e = 97

a = j + 5

e = 2j

j + j + 5 + 2j = 97

4j + 5 = 97

4j = 97 - 5

4j = 92

j = 92/4

j = 23 < = = = what Jenny has

a = j + 5

a = 23 + 5

a = 28 < = = = what Ali has

e = 2j

e = 2 (23)

e = 46 < = = = what Eric has

So make them all x

Jenny = x

Ali = x+5

Eric - 2x

2x + x + 5 + x = 97

4x = 97 - 5

x = 23

Jenny has 23

]Ali has 28

Eric has 46
