Puff ‘n’ Stuff Services is a small company that assembles
mailings for clients in the Atlanta area. Different-size en-
velopes are stuffed with various items such as coupons, ad-
vertisements, political messages, and so on, by a staff of
workers, who are paid on a piece-rate basis. A time study of
a job has been conducted by an engineering consulting firm
using a subject stuffing manila envelopes. The observations
from the time study for 10 cycles of the five-element job and
the performance rating for each element are as follows.
a. Using an allowance factor of 10%, compute the stan-
dard time for this job.
b. If the firm pays workers a piece rate of $0.03 per enve-
lope for this job, what would the average worker make
per hour, and what would the subject of the study make
per hour?
