Answer:
[tex]\textbf{Price of 1 gallon of gas in our area : }\bf x=\frac{P}{15}[/tex]
Step-by-step explanation:
Let the price of 1 gallon gas = $x
Capacity of gas tank of the car = 15 gallons
Total price for filling the car tank = $ 15·x
But the price for filling the tank is given to be $P
⇒ 15·x = P
[tex]\textbf{So, price of 1 gallon of gas in our area : }\bf x=\frac{P}{15}[/tex]
