Edit Woocommerce Pricing Formula

I need to edit the way woocommerce calculates the price on a client’s website. It’s a site that allows customers to purchase products on credit by choosing the number of months they wish to make payment. However, in the cart, if the customer selects 2 or more of the quantity of the product they wish to purchase, the total amount of the products appears in the "Price" column of the cart instead of the unit price of that product. I would like to edit it such that the unit price shows in the price column no matter the quantity selected and then the total amount can then show in the total and subtotal columns. I have tried editing the woocommerce cart file and a couple of others but nothing seems to work. This is the site: www.appliancepointgh.com Any help on how i can do this would be deeply appreciated.
