Auston,Ben and carl spent all their mone on a dinner which cost $60. Auston paid thrice amount of money paid by Ben and Carl. Ben paid $1.60 more than Carl. If they were to share the cost of the dinner equally, how much must Ben and Carl each return to Auton?

Carls' share  x
Ben's hare  x+1.6
Auston  3(x + x+1.6)
solve
x + x+1.6 + 3(x + x+1.6) = 60
