One of the operations in the United States Postal Service is a mechanical mail sorting operation. In this operation, letter mail
is sorted at a rate of one letter per second. The letter is mechanically sorted from a three-digit code input by an operator sitting at a keyboard. The manager of the mechanical sorting operation wishes to determine the number of temporary employees to hire for December. The manager estimates that there will be an additional 35,100,000 pieces of mail in December, due to the upcoming holiday season.
Assume that the sorting operators are temporary employees. The union contract requires that temporary employees be hired for one month at a time. Each temporary employee is hired to work 150 hours in the month.
a. How many temporary employees should the manager hire for December?
b. If each employee earns a standard $16 per hour, what would be the labor time variance if the actual number of letters sorted in December was 34,020,000? Use the minus sign to enter favorable variances as negative numbers.
