Is there a function that will look through a column of data (eg column A), find any cells that match another specified cell (eg C1) and sum the values of the corresponding cells in column B next to the matched cell?

I know that's confusing, let me use any example:

A__________B__________C
_____________________AAPL
AAPL_______25
CMI________30
INTU_______40
MON________5
AAPL_______100
EBAY________60

So, I want the function to look through the list in column A and return the sum of the values that match the specified value (AAPL in column C). So here, the answer would be 125 (25+100).

Thank you very much for your help and please respond with questions if you don't understand what I am asking!
