Write out each item string to file named inventory_items.txt.

Read in the lines of text and split up string line into a list. Access the appropriate list elements in order to perform the following calculation for the profit: number_sold * (price_item - cost_item). Print out the name of the item and the profit with two decimal places of precision.

Sum up the profit in order to compute the total profit.
