An existing insurance application process requires manual keying of three different forms by a team of data entry operators.
 
  The three forms' input times appear in the following table along with the numbers of each type of form anticipated for the coming year. A proposed refinement in the process would reduce the number of forms but make each slightly longer. This would be combined with a search of public records on the World Wide Web as necessary. These times and quantities appear in the lower half of the table. If the labor rate for the data entry operators is the same, which method is preferable?
