Need help inputting values with switch statements.

MisterBren (24)
Hello, I'm currently writing a program that determines the cost of a travel based on travel distance, mpg, gas type, and either state (Michigan or Ohio). I am given values of the price of each gas type (regular, midgrade, and premium) for each state.

Michigan -
regular: 2.27
midgrade: 2.49
premium: 2.70

Ohio -
regular: 2.28
midgrade: 2.46
premium: 2.55

I've done everything so far and it works when I run it, besides the ending "total travel cost." I can't figure out how to input the prices of gas for whatever choice the user makes. Does this make sense? Thanks!

You can set the prices before the break for each case.
