I would like to create a formula in one cell that would calculate amounts in
a given range. For example:

Column A Column B
Apples $10
Oranges $20
Bananas $15
Apples $10
Pears $50
Apples $10

From the chart above, I can see that the amount spent on Apples was $30. I
would like to create a formula that would lookup Apples in column A and total
the corresponding amount from column B (without having to sort column A).

Any help is greatly appreciated. Thank you!
