Questions: The total revenue by Dell for the financial year after looking at the management discussion and analysis of the financial statements was $56,940. Assume that $3 billion of operating expense in addition to the depreciation and amortization are all the fixed expenses, Compute the average variable cost of goods sold percentage. Compute the average contribution margin percentage. What would be the break-even sales dollars under this scenario?

Here is what I have come up with. I have found tons of answers but they are all the same and don't make sense to me as operating expenses and amortization are fixed and not variable cost.

By looking at the Consolidated Statement of operation, the cost of goods sold of Dell was $44,754 million and the selling, administrative and engineering expenses were $9,174 million. In addition, the depreciation and amortization for 2013 was of $1,144 million. Assuming that dell has $3 billion (3,000 millions) of operating income, I came up with the numbers below:

Variable Cost of Goods Sold = Cost of Goods Sold + Variable Cost – Fixed Cost = 44,754 + 53,928 – 4,144 = $94,538 USD

Average variable cost of goods sold % = Variable Cost of Goods Sold /Sales Revenue = 94,538 / $56,940 = ???

Average contribution margin = Sale price – Variable costs = Sales Price – (cost of goods sold + adm expenses + engineering expenses) = $56,940 – (44,754 + 9,174) = 56,940 – 53,928 = $3,012 USD average contribution margin

Contribution Margin Ratio = Contribution Margin / Sales Price = 3,012 / 56,940 = 5.289 %

Break-Even Sales in units = Fixed Expenses / Contribution Margin Ratio = ($3,000 + $1,144) / 5.289% = $4,144 / 5.289% = $78,351.29 units.

1. Suppose that a local non-profit organization rans a program in two parts of the city: east and west El Paso.
