Basic Math Help

RichieD

Hi guys,

I wonder if anyone could any help me come up with a function for a program im writing?

So essentially I have 3 groups of customers,

1. Prefer to buy low priced Items
3. Prefer to buy high priced Items
2. Between 1 & 3

I then have a list of items which can have any price, so I need to work out a % chance of the customer buying the item.

Examples

Customer category 1 - Item price €1 = High chance to buy
Customer category 1 - Item price €100 = low chance to buy
Customer category 3 - Item price €1 = Low chance to buy
Customer category 3 - Item price €100 = High chance to buy

They dont need to be based on the actual amounts, just that the lower the price the more chance customer category 1 will buy it, the higher the price the higher the chance customer category 3 will buy it and 2 being in the middle ground.

Any help would be appreciated.

Thanks

ProbToBuy(Customer,Product)
{
    maxprice = 100; // set your maximum price here or you get probabilities > 1
    
    if (Customer.type == Type1)
    {
        return Product.price/maxprice;
    }
    else if (Customer.type == Type3)
    {
        return 1 - Product.price/maxprice;
    }
    else
    {
        return 1 - ( 2 ( AbsoluteValue ( maxprice/2 - Product.price ) )/maxprice );
    }
}
