A companys contribution format income statement for last month is given below:

Sales (40,000 units $21 per unit)	$	840,000
Variable expenses		588,000
Contribution margin		252,000
Fixed expenses		201,600
Net operating income	$	50,400

The company considers renovating its operations by purchasing a new machine that would reduce variable expenses by $6.30 per unit. However, fixed expenses would increase to a total of $453,600 each month. Using the new machine would not cause a change in monthly sales quantity or price per unit. What would the company's margin of safety in dollars be if it purchases and uses the new machine?
