Benton’s gas station price is $1.25 per gallon. Betsy’s gas station price is $20 per 35 gallons.

How much does 20 gallons cost at each store? Which one costs less?

Answer :

To find out how much 20 gallons costs at each gas station, let's calculate the cost separately for each.

  1. Benton’s Gas Station:

    • The price per gallon is $1.25.
    • To find the cost for 20 gallons:

    [tex]\text{Cost} = 20 \times 1.25 = 25 \text{ dollars}[/tex]

  2. Betsy’s Gas Station:

    • The price for 35 gallons is $20.
    • First, find the cost per gallon:

    [tex]\text{Cost per gallon} = \frac{20}{35} \approx 0.57 \text{ dollars per gallon}[/tex]

    • Then, find the cost for 20 gallons:

    [tex]\text{Cost} = 20 \times 0.57 = 11.4 \text{ dollars}[/tex]

Comparison:

  • Benton’s Gas Station charges $25 for 20 gallons.
  • Betsy’s Gas Station charges $11.40 for 20 gallons.

So, Betsy’s Gas Station is cheaper for 20 gallons of gas.
