Question

3. Gasoline costs $3.586 per gallon. Your car gets 24 miles to one gallon of gas. The distance from your home to

your favorite camping site is 280 miles. What will be the cost of the gasoline for a round trip to the campsite?

Answer 1

Answer: 83
`(101)/(150)`

Explanation:

First put the numbers into an equation.

A round trip would mean to and fro, we are finding the cost of 280 miles times 2 which equals 560 miles.

We know one gallon gives us 24 miles and since the total is 560 miles, we can do
`(560)/(24)` to get the total number of gallons of gas used on the round trip which we would get 23
`(1)/(3)`.

Now we multiply 23
`(1)/(3)` to 3.586 to get the total cost of all 560 miles. And the product of 23
`(1)/(3)`·3.586 would equal approximately 83.6733333333 or 83
`(101)/(150)`.

Hope that helped.
