b. How much time will it take to produce the next 90 units?
c. How much time will it take to make the 100th unit?

2. In an attempt to increase productivity and reduce costs, Rho Sigma Corporation is planning to install an incentive pay plan in its manufacturing plant. In developing standards for one operation, time study analysts observed a worker for 30 minutes. During that time the worker completed 42 parts.

a. What is the normal time for the task?
b. What is the standard time for the task?
c. If the worker produced 500 units during an eight-hour day, what wages would the worker have earned?
