$120 is shared among 3 friends Ava, Ben, and Carlos. If Ava receives $20 less than Ben, and Ben receives 3 times as much money as Carlos, how much money does Carlos receive?
Let X be the amount of money Ben receives, so Ava has X-20, Ben has X, and Carlos has X/3. So 7/3x-20= $120. Solving for X, we get $60. If Ben recieved $60, then Carlos recieved $60/3= $20.
Hope it helps!
