If I read it right, you just sum the weights and then divide the
weight of each truck by the sum to normalize the values. And the
fraction is the percentage of fixed cost each truck would pay. So say
you have 3 trucks with weights 4, 6 and 9. They sum up to 19 so Truck
1 pays 4/19, Truck 2, 6\19 and Truck 3, 9\19 or 21%, 32% and 47%
respectively. I'm sure you can do the simple calcs. in Excel without
my help.
