An online shopping site lists the shipping charges for ordered items. The site provides free shipping under the following conditions:

  • The number of items ordered is 4 or more and the checkout total is $300 or more.
  • Standard shipping is selected (4 or 5 business days from the date of purchase).

The following are the shipping rates under these conditions:
