Basic Algorithm Help

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

double likelyhoodToBuy;
switch(customerType) {
    case Customer.CHEAP:    likelyhoodToBuy = 100 - (itemPrice * (100/1)); 
                            break;
    case Customer.MODERATE: likelyhoodToBuy = (itemPrice * (100/1)) / 2;
                            break;
    case Customer.LAVISH:   likelyhoodToBuy =  itemPrice * (100/1);
                            break;
}

return likelyhoodToBuy;
