I have two items in the cart item 1= $70 and item 2= $100 and i also have the total shipping i can charge, which is $15. While accepting this order Im trying to split the $15 shipping between item1 and item2 in a weighted manner based on the price. What is the best algorithm to split this and what is the logic/calculation look like ?
Any thoughts helpful, thanks !
I don't know Java, but since you included no Java code, I'll just give pseudocode to how to do this:
a = 70 / (70 + 100)
b = 100 / (70 + 100)
This normalizes the two values, and then you can just multiply a and b with $15 to get the proper ratio. In this case, a is 0.41 and b is 0.59
Then:
ratio_item_a = 15 * a
ratio_item_b = 15 * b
ratio_item_a is 6.18 and ratio_item_b is 8.82
