Answer:

$150.66

Explanation:

Let that amount of money Roger has = x

The amount of money Roderick has = y

Roger has four dollars more than double the amount that Roderick has in his wallet.

x = 2y + 4

Together, they have a total of $224.

x + y = $224....... Equation 1

We substitute 2y + 4 for x in Equation 1

2y + 4 + y = $224

3y + 4= $224

3y = $224 - 4

3y = $220

y = $220/3

y = $73.333333333

y = $73.33

How much money does Roger have?

x = 2y + 4

x = 2(73.33) + 4

x = $146.66 + 4

x = $150.66

Roger has $150.66
