Question

4. Calculate the cost of gasoline for a 420 mile trip if your car averages 20 miles/gal of gas, and thegas costs $2.95/gallon. (Hint: you need to convert miles to dollars)dollars

Answer 1

It is given that the trip is 420 miles and the car averages 20 miles per galon of gas.

The cost of gasoline is $2.95 per gallon.

First calculate the number of gallons of gas required for the trip, let it be g, so it follows:

`g=(420)/(20)=21`

Hence 21 gallons of gas is required for the trip.

Let the cost of gasoline be c so it follows:

`c=2.95*21=61.95`

Hence $61.95 will be the gasoline cost for the trip.
