how to predict response rate or responses in Rapid Miner

Hi All,

I'm fairly new to Rapid Miner and looking for a way to predict response rate based on historical data from past 2 years.
I have customer id and categories and of course quantity mailed and responses 

for example

id    category     state   year   month     QtyMailed    Responses Received            Response Rate
1        a                OH    2018    oct           5000                  200                                    4%                          
1        b                CA    2018    Nov          10000               130
1        c               PA     2018    dec           35000               512
