If your car gets 35 miles per​ gallon, how much does it cost to drive 400 miles when gasoline costs ​$3.30 per​ gallon?
Arlecino [84]
To solve his equation start by finding how many gallons of gas you need to purchase for the total trip.
Set up an expression that divides the total distance of the trip by the miles received per gallon.
This gives you:
400 / 35

Divide to get 11.43 gallons.

To find the cost of this, multiply the total number of gallons needed to cover the trip by the cost of each gallon.
Set this up in another expression.
This results in:
11.43 x 3.30

Multiply the values to find the total cost.
This leaves you with:
37.72

So, the total cost for gas for a 400 mile trip on 35 miles per gallon is $37.72.

I hope this is correct and helps you! :)
