Help me lol Option 1: You can take a broomstick to Hogwarts but there is a $75 flat fee plus it costs $2 per mile.

Option 2: The storeowner has a potion you can take that will turn you in to an owl so you can fly there, but it costs $4000 and only lasts for 3900 miles and then you would have to take the Hogwarts express the rest of the way for $1 per mile.

After how many miles is the cost the same?
