Answer:
Results are below.
Step-by-step explanation:
First, we need to calculate the unitary contribution margin:
Unitary contribution margin= 100*0.25
Unitary contribution margin= $25
Now, we can calculate the break-even point in units and dollars:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 104,000 / 25
Break-even point in units= 4,160
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 104,000 / 0.25
Break-even point (dollars)= $416,000
Finally, the margin of safety in dollars as a ratio:
Current sales= (26,000 + 104,000) / 25
Current sales= 5,200
Margin of safety= (current sales level - break-even point)
Margin of safety= (5,200*100 - 416,000)
Margin of safety= $104,000
Margin of safety ratio= (current sales level - break-even point)/current sales level
Margin of safety ratio= 104,000 / 520,000
Margin of safety ratio= 0.2 = 20%
