Okay, imagine you go to the store to buy candy. You see all the different types of candy and their prices displayed in front of you, so you can choose the one that you like and can afford.
The gasoline price website is like that store for gasoline. Except, instead of candy, there are different kinds of gasoline that you can buy for your car. And just like candy, the prices of gasoline can vary from one gas station to another.
The website shows you the prices of gasoline at different gas stations around your area, so that you can choose the one that has the lowest price. It also tells you the type of gasoline available at each gas station, like regular, premium, or diesel.
So, next time your parents need to fill up their car with gasoline, they can use the gasoline price website to find the cheapest option near them, just like you find the cheapest candy at the store!
