How many tests can I get from a roll of RBT IV printer Paper?

A roll of RBT IV printer paper is approximately 24 ft long.  The RBT IV prints three consecutive copies of each test for a total length of about 5 1/2″.  The operator then cuts the three tests apart to fasten one result to each of the three copies of the Alcohol Test Form.  Therefore, one roll of RBT IV printer paper will yield approximately 50 tests, with a test result fastened to each of the three copies of the Alcohol Test Form.
