How much would it cost to drive an automobile that averages 22 miles per gallon of gasoline that travels 12,500 miles each year, and gasoline costs $2.85 per gallon? I don't know how to write the conversions for this one, because there's nothing that could be on it's on like a would a x b/a. Please help and thanks.

12,500 / 22 = 568.1818 gallons

568.1818 * 2.85 = $1,619.32

To calculate the cost of driving the automobile for a year, you need to consider two factors: the average miles per gallon (mpg) and the cost of gasoline per gallon.

First, let's calculate the number of gallons of gasoline needed to travel 12,500 miles. You can use the formula:

Number of gallons = Total miles / Average mpg

Given that the automobile averages 22 miles per gallon and travels 12,500 miles:

Number of gallons = 12,500 miles / 22 mpg

To find the cost, multiply the number of gallons by the cost per gallon:

Cost = Number of gallons x Cost per gallon

Given that the cost of gasoline is $2.85 per gallon:

Cost = (12,500 miles / 22 mpg) x $2.85

Now, let's calculate it:

Cost = (12,500 / 22) x $2.85

Cost ≈ 568.18 x $2.85

Cost ≈ $1,620.68

So, it would cost approximately $1,620.68 to drive the automobile for a year, considering the given average mpg and the cost of gasoline per gallon.
