Question

suppose a car uses one gallon of gasoline for every 20 miles traveled. if a gallon of gasoline costs $2.75, how much will the gasoline cost to travel 300 miles in the car? a $22.00 b $27.50 c $32.75 d $41.25

Explanation:

Step1: Find gallons needed for 300 miles

To find the number of gallons of gasoline required to travel 300 miles, we use the rate of 1 gallon per 20 miles. So we divide the total miles (300) by the miles per gallon (20).

$$ \text{Gallons} = \frac{300}{20} = 15 $$

Step2: Calculate total cost

Now that we know we need 15 gallons, and each gallon costs $2.75, we multiply the number of gallons by the cost per gallon to find the total cost.

$$ \text{Total Cost} = 15 \times 2.75 = 41.25 $$

Answer:

D. $41.25
