MR. store who runs a photocopy business working eight hours per day, processes 100 scripts in a day. he estimates his labor cost to be 9 euros per hour. Also, he has estimated that the total material cost for each script is approx. 2 euros while the daily expenses are 28 euros. calculate the multi-factor productivity.

in an effort to increase the rate of the photocopy process to 150 scripts he decides to change the quality of ink, thereby raising the material cost to 2.5 euro 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 multi-factor productivity, by what amount should the material costs need to be increased?
