Assignment 5: Postage rates

due Monday 2/11

Write a program that calculates postage for mail sent within the United States. The program should prompt the user for the weight of a piece of mail (in ounces), then display the correct amount of postage.

Here are the basic postage rates you will need to use:

A letter weighing one ounce or less costs 34 cents.
Each additional ounce (or fraction thereof) costs an additional 23 cents.

To handle decimal parts of ounces correctly, you will need to use a rounding operation. Here are some hints on rounding.

Extensions

For 10 points: For items that weigh more than 13 ounces, there is a different set of postage rates, called Priority Mail Rates. Make your program correctly handle these rates, which are listed on the USPS site.
