Pieces processed per hour 1,000 2,000 3,000
Number of workers per hour 10 5 2
Hourly wage rate \$5.50 \$10.00 \$12.00
Overhead rate per hour \$10.00 \$25.00 \$50.00

b) Workers in Center 2 are scheduled to receive a 10% pay raise next month. What will be the change in the multifactor productivity rate? Also, what is the percentage change in the multifactor productivity performance?
c) A new processing machine is available for Center 1 that would increase the output to 1,500 pieces an hour at an additional overhead rate of \$30.00 an hour. Merrifield will only install the new processing machine if it increases the multifactor productivity of Center 1 by at least 2.5%. Should Merrifield install the new processing machine? Justify your answer. Also, what is the percentage change in the multifactor productivity performance?
