Question

If your car gets 24 miles per gallon, how much does it cost to drive 390 miles when gasoline costs $2.70 per gallon? The cost is $43.90 (Simplify your answer. Round to the nearest cent as needed.)

Answer 1

$43.88

Step-by-step explanation:

First, we will calculate how many gallons will you need to drive 390 miles. So, if the car gets 24 miles per gallon, we get:

`390\text{ miles}*\frac{1\text{ gallon}}{24\text{ miles}}=16.25\text{ gallons}`

So, the car gets 390 miles with 16.25 gallons. Then, if the cost per gallon is $2.70, the total cost rounded to the nearest cent is:

`16.25\text{ gallons }*\text{ \$2.70 = \$43.88}`

Therefore, the cost is $43.88
