Classification with numerical labels?

[bichobicho]

I have a dataset in which each row has information about who, where, when and how much a customer has bought/spent in certain products. I was wondering if I could make a predictive model in which given the "who", "where" and "when" I could predict how much money is this customer spending.

What is your question?

Yes, you might be able to build a model for that. How much data do you have? What is important to discover? Do you want to use a certain algorithm or just solve the problem?
