How do I apply multiple formulas to one column?

Ie if C=Bananas, if true, ExB34

if C=Apples, if true, ExB35

if C=Grapes, if true, ExB36

The E column being Quantity and B column being the Current Price

I want to apply all 3 formluas to 1 column dependant on the C column answer

I have tried if C=Bananas, if true, ExB34(&)C=Apples, if true, ExB35(&)C=Grapes, if true, ExB36

but I am getting a syntax error please help :)
