1. Months with 30 days are September, April, June, November. February has 28 days. The other months
have 31 days. Print the name of the month when given the number of days in the month.

2. Amazon.com the online retailer, has this policy for determining if a customer order is tax- exempt.
Determine if a customer order is tax exempt based on this policy:
“If tax has been charged on any portion of your order and you need to take advantage of your tax exempt
status, the process will differ depending on the merchant who sold the taxed items. If the taxed items
were sold by any of the following merchants, Amazon Customer Service can facilitate a refund.
• Amazon.com LLC
• Amazon Digital Services, Inc.
• Borders Teamed with Amazon.com, Inc.
• Target.com
If the taxed items were sold by any other merchant, please contact that merchant directly using the
contact information provided in the merchant's Contact Customer Service section. In those cases where
Amazon.com can facilitate a tax exempt refund, you will need to provide us with acceptable proof of
exempt status for the state where the items will be shipped.“


3. Determine if sales tax applies to a purchase based on this information:
United States Government Purchasers Sales tax does not apply to purchases made by the United States
