I have to take a 4-digit number and calculate it like this:
First 70 cubic meters $5.00 minimum cost
Next 100 cubic meters 5.0 cents per cubic meter
Next 230 cubic meters 2.5 cents per cubic meter
Above 400 cubic meters 1.5 cents per cubic meter
Soo, for the number 203, it would calculate $10.83. Ok, I've set it up numerous ways, and can't get anywhere near the correct price. Basically what I need to know is -- How can I break up one number into those 4 different calculations?
