The initial investment of $12,600 will be depreciated straight-line over its useful life of 6 years to a final value of zero, and the discount rate is 13%.
Required:
a. What is the degree of operating leverage of Modern Artifacts when sales are $30,800?
b. What is the degree of operating leverage when sales are $57,120?
