Answer: C.$221.86
Step-by-step explanation:
Contribution Margin is the difference between the sales price and the variable costs.
Best case scenario of Sales would mean it is the higher amount.
Best case scenario of costs would mean the lower amount.
Best case Sales
= 349 * ( 1 + 3%)
= $359.47
Best Case Variable Cost
= 139 * ( 1 - 1%)
= $137.61
Best Case Contribution Margin
= Best case Sales - Best Case Variable Cost
= 359.47 - 137.61
= $221.86
