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 $$7,000$ above the cost of a traditional vehicle. On average, the hybrid will get $60$ miles per gallon of gas, and the traditional

car will get $30$ miles per gallon. Also, assume that the cost of gas is $$2\mathrm{.}40$ 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, e$.$g$.0\mathrm{.}25.)$
