What is the total amount of postage required to mail the package?

W: Do I have enough postage on this package?
M: Let’s see. You already have three fifteen cent stamps and two twenty-five cent stamps on it. You only need one five-cent stamp.

M: I heard you had got a wonderful job in a post office. How’s your new job going?
W: Not so well, I’m afraid. I just feel like a fish out of water. People there are rather strange to me.
