Let x represent the amount received by the runner up.
Given that the winner receives three times as much as the runner-up, it means that
amount received by winner = 3 * x = 3x
Given that total amount = 60000, then
3x + x = 60000
4x = 60000
x = 60000/4
x = 15000
Runner up receives $15000
Winner receives 3(15000) = $45000
