range

Hi,

I want to calculate the amount to charge my customers, when they buy licenses of my product. I sell it in ranges of licenses:

1-10 : $50/user
11-20 : $40/user
21-30 : $30/user
31-50 : $20/user

So when someone purchases 136 licenses, I will charge him:

100 X $20 = $2000
30 X $30 = $900
6 X $50 = $300

How can I do this in plain C# or LINQ?

Thanks in advanced.

Interview question: f(f(n)) == -n

A question I got on my last interview: Design a function f, such that: f(f(n)) == -n Where n is a 32 bit signed integer; you can't use complex numbers arithmetic. If you can't design such a function for the whole range of numbers, design it for the largest range possible. Any ideas? >>> More
