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

To solve this problem, let's break it down step by step:

Let's assume Carl paid x dollars.
According to the given information, Ben paid $1.60 more than Carl, so Ben paid (x + $1.60).
And Auston paid three times the amount paid by Ben and Carl, so Auston paid 3 * (x + $1.60).

We know that together they spent $60 on dinner, so we can write the equation:
x + (x + $1.60) + 3 * (x + $1.60) = $60

Now let's solve for x:

Combine like terms:
6x + $6.80 = $60

Subtract $6.80 from both sides:
6x = $60 - $6.80
6x = $53.20

Divide both sides by 6 to isolate x:
x = $53.20 / 6
x = $8.87 (approximately)

Now we know that Carl paid approximately $8.87.

To find out how much Ben paid, we can substitute this value back into the equation:
Ben paid x + $1.60
Ben paid $8.87 + $1.60
Ben paid $10.47 (approximately)

Since they are splitting the cost equally, we need to calculate how much Ben and Carl need to return to Auston.

The total amount they need to return is the difference between what they paid and the equal share for each person.
The equal share for each person is the total cost divided by the number of people, which in this case is $60 / 3 = $20.

For Ben:
Amount to return = $10.47 - $20 = -$9.53 (approximately)
Ben needs to return approximately -$9.53 to Auston.

For Carl:
Amount to return = $8.87 - $20 = -$11.13 (approximately)
Carl needs to return approximately -$11.13 to Auston.

Note that the negative sign indicates that they owe money to Auston.
