Alex wants to buy a new car. He looks at a gas car and an electric car. He needs to decide which one is better for him. He thinks about the total price.
Alex knows the cars have different prices. But he also thinks about the fuel. Gas cars use gasoline. Electric cars use electricity. Which fuel is cheaper?
The answer is not simple. The cost is different in every state. In a state like Washington, it is much cheaper to drive an electric car. This is because electricity is not expensive there.
But in a state like Hawaii, the story changes. Electricity is very expensive. A gas car can sometimes be cheaper to drive. Alex knows he must check the prices where he lives.
