Answer:
$450
Step-by-step explanation:
Let E be the amount of money Ethan starts with, J be the amount Jun Wei starts with, and R be the amount Raj starts with. Let M be the total amount of money to start with.
To start:
This means Ethan has 5/20 of M, the money to start with. This reduces to 1/4 of M.
Afterwards:
This means Ethan has 3/13 of the remaining money (which is M-50!) after giving up 50. So
E = (M/4), or 4E = M
and
We know 4E = M, so we can substitute that in:
That's how much money Ethan had to start with. But we're asked how much he has AFTER giving $50 away, so that's $450.
