Question

1. mildred wants to figure out how many gallons of gas she used and how much the gas would cost if the cost per gallon is $2.70. she wants to take a 400 mile road trip and she knows her car gets 25 miles per gallon of gasoline. how much will the gasoline cost her?

Explanation:

Step1: Find gallons of gas used

To find the gallons of gas used, we use the formula: Gallons = Miles ÷ Miles per Gallon. Here, miles = 400 and miles per gallon = 25. So, Gallons = \( \frac{400}{25} = 16 \) gallons.

Step2: Calculate total cost

To find the total cost, we use the formula: Total Cost = Gallons × Cost per Gallon. Here, gallons = 16 and cost per gallon = $2.70. So, Total Cost = \( 16 \times 2.70 = 43.2 \) dollars.

Answer:

The gasoline will cost her $43.20.
