I am trying to create a simple formula without using a data validation list.

1. Is it possible
2. If NOT how do you create in data validation

I have tried this formula inside and outside of data validation, Googled till my fingers bled and can't find what I am looking for.

A17= Number 1 or higher
Statement tried but receive an error

=IF(A17>=25,"24.95","34.95")

My goal is IF A = 25 or greater then price is 24.95, If False then 34.95

Thanks in Advance
