PLEASE I NEED HELP WITH 1.12 & 1.13.

1.12 The State department of motor vehicle, attempts to perform an analysis of the driver's licence renewal operations. In the past each renewal process followed six steps to be performed and took one hour to finish. Calculate the daily productivity, assuming that the working time is eight hours per day. In an effort to improve performance, State department reengineered the whole process, i.e. eliminated some steps, merged some others, etc. As a result the renewal time of each process dropped to half-hour. However, from time to time during the day, there are some unexpected failures, which result in delays up to an hour per day. Has the modified process impact productivity? 1.13 Mr Store who runs his photocopy business working 8 hours per day process 100 scripts. He estimates his labour cost to be 9 per hour. Also he has estimated that the total material cost for each script is approximately 2; while the daily expenses are 28. Calculate the multifactor productivity. In an effort to increase the rate of the photocopy process to 150 scripts, he decides to change the quality of ink thus raising the material cost to 2.5 per day. Is the new productivity better than before? If Mr Store would like to increase the photocopy process to 150 scripts without sacrificing the initial multifactor productivity, by what amount has the material costs to be increased
