I have a worksheet that is set up as follows,

Column A Product ID
Column B Product Name
Column C Product Quantity in Stock
Column D Product Price

I would like a formula that I can place in Column E that will take the
quantity of product in stock in Column C and multiply that number by the
product price in Column D then drag that formula down to the end of Column E
so that every row will have a separate total depending on the quantity in
stock and the Product price. The at the bottom of Column E I can do a
=sum() to get a total price of all products in stock.

Thanks in advance
