I apologize if this is a duplicate submission.

I have a spreadsheet of data with two columns of data for which I need to
summarize on another spreadsheet. Column A lists makes/models and Column B
counts the number sold. The original spreadsheet will contain multiple
duplicate entries of the same makes/models for which I need to summarize.

Ex:
Column A Column B
7444 loader 2


Which formula would be best for this project?

Thank you!
