The document discusses labor productivity and multifactor productivity calculations for two problems. For problem 13, labor productivity is calculated as 160 valves produced in 8 hours of work, which equals 20 valves per hour. For problem 14, labor productivity is calculated as 65 rugs produced in 520 hours of work, which equals 0.125 rugs per hour. Multifactor productivity is calculated as 65 rugs divided by the total costs of $500 for solvent, $1000 for machine rental, and $6760 for 520 hours of labor, which equals 0.00767 rugs per dollar.

1. Practical Lesson 01
Problem 13
We have 160 valves produced in a day, with 8 hours work.
Labor Productivity = / = 160/8 = 20 valves/hour
Problem 14
65 rugs
520 hours
Labor Productivity = / = 65/520 = 0.125 rugs/hour
Solvent = 500 dollars
Machine Rental = 1000 dollars
Labor costs = 520*13 = 6760 dollars
Multifactor productivity = /( + + ) = 65/(500 + 1000 + 6760) = 0.00767
