10 cents per minute for the first 3 minutes + 30 cents, but I don't know what is 10-cents for each minute thereafter?

type mistake:

10 cents per minute for the first 3 minutes = 30 cents

10 - 3 = 7

This problem doesn't make sense as the charge per minute is the same -- whether it's the first three minutes or the rest of the phone call.
