Adding Up Dollar Amounts?

Ok, in my previous post I figured out how to get excel to total the numbers I have

Now my question is how to do I get my products a dollar amount, and then have it total the amount

So on the left hand side i have a list of 20 products. Ive found the formula to add up the total per customer

Now i want to give each item a dollar value so not only will I have the total number of items sold, but ill have the total dollar amount

Right click -> Custom format -> Currency -> choose $
