Final answer:
By calculating the price per gallon at both gas stations, it is determined that Fred's Gas, at $2.15 per gallon, has cheaper gas compared to George's Gas which sells it at $2.21 per gallon.
Step-by-step explanation:
To determine which gas station has cheaper gas, we need to calculate the price per gallon at each gas station and compare them.
At Fred's Gas, one driver buys 12 gallons of gas for $25.80, which gives us a price per gallon of $25.80 ÷ 12 = $2.15.
Another driver buys 15 gallons of gas for $32.25, resulting in a price per gallon of $32.25 ÷ 15 = $2.15, confirming the price per gallon at Fred's Gas remains consistent.
At George's Gas, the cost of gas is represented by the equation y = 2.21x, where y is the total cost, and x is the number of gallons.
This equation shows that the price per gallon at George's Gas is $2.21.
Comparing the two prices, we find that Fred's Gas has a price of $2.15 per gallon while George's Gas has a higher price of $2.21 per gallon.
Therefore, Fred's Gas is the station with cheaper gas prices.
