Ok if Dan made 1412.42 and Aaron made 1187.92

And total amount of fuel for the truck was 418.91 how do fuel do I deduct for each driver? They both driving the same truck. I need to know how to divide the fuel evenly

First we should calculate the relation between how much they make and the fuel cost so we write

(1412.42 + 1187.92) / 418.91=6.21

So that means that for every 6.21 dollars made 1 dollar of fuel must be deducted so now we calculate what they need to be deducted by:

Dan deduction = 1412.42/6.21 = 227.41

Aaron deduction = 1187.92/6.21 = 191.29
