To find the break-even point, we need to know the total revenue and total cost for producing and selling 30,000 computers.

Total Revenue = Selling Price x Number of Units Sold

Total Revenue = 700 x 30,000

Total Revenue = 21,000,000 birr

Total Cost = Fixed Cost + Variable Cost

Total Cost = 5,000,000 birr + 6,000,000 birr

Total Cost = 11,000,000 birr

Now, we can calculate the break-even point using the formula:

Break-even point = Total Cost / Selling Price per unit

Break-even point = 11,000,000 / 700

Break-even point = 15,714.29

Therefore, the break-even point is 15,714 units. This means the company needs to sell at least 15,714 computers to cover its total costs. Any sales over this number will result in a profit.
