TCL script Need Help to Optimise If and also Correction of the 3rd Output

I have the following code, and would like to know how to:

1) Optimise the "if", so in future if I have 10 new customer_id, I don't have to write 10 time the if-then-else statement, any suggestion?

2) Notice the output for no.3 its wrong, it should not be calculating (divide 1.5) how do I correct it?
