Cost-volume-profit analysis can also be used in making personal financial decisions. For example, the purchase of a new car is one of your biggest personal expenditures. It is important that you carefully analyze your options.

Suppose that you are considering the purchase of a hybrid vehicle. Let's assume the following facts. The hybrid will initially cost an additional $6,500above the cost of a traditional vehicle. The hybrid will get30miles per gallon of gas, and the traditional car will get18miles per gallon. Also, assume that the cost of gas is $1.80per gallon.

Using the information in part (a), if "miles" is your unit of measure, the "contribution margin" of the hybrid vehicle relative to the traditional vehicle? That is, the variable cost savings on a per-mile basis.(Round answer to 2 decimal places, e.g. 0.25.)
