calculates the total cost with javascript

I am struggling trying to figure this out. I can't seem to comprehend it quite yet. Can anyone help me put this together? thanks in advance!

You are hired by a small grocery store. Your assignment is to create a page that asks the user for 3 pieces of information: item name, item price, and # of products. It displays to the user:

* a page heading
* an image
* a table with the following information in it:

* product name
* product price
* # of items
* total cost of the purchase

Program operation
The program asks the user for 3 pieces of information using prompts: product name, product price, and # of items purchased.

The program then calculates the total cost of the purchase. It then displays all the information it has in a web page as shown below. For this display, the user entered loaf of bread, 3, and 2.99 into 3 prompts.

You can't just post your assignment without even trying ! , actually i don't understand what is your problem with javascript .
