need help with the variable cost for this thank you

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 $8,100 above the cost of a traditional vehicle. On average, the hybrid will get 55 miles per gallon of gas, and the traditional car will get 30 miles per gallon. Also, assume that the cost of gas is $3.30 per gallon. Using the facts above, answer the following questions. (a) For gasoline, what is the unit variable cost of going one mile in the hybrid car? What is the unit variable cost of going one mile in the traditional car? (Round answers to 2 decimal places, es. 0.25.)
