Solution
Labor productivity before purchase of new equipment:
 Number of labor works= 4
carts per hour= 80
average production per one worker= 80/4= 20 carts
after purchase of new equipment:
avaerage production per one worker= 80/3= 26.67 (round it as 27 units)
b. The cost of production, before purcahse the equipment:
Labor cost per hour =$10
Machine cost per hour= $40
total working hours are= 8 hours
total cost per 8 hours= 8*4*10+8*40= $320+$320= $640
(total labor* number of working hours* cost per hour+machine hours*cost per hour)
total cost after new equipment purchase=
Labor cost= 8*3*$10= $240
Machine cost= 8*$50= $400
total cost after new equipment purchase= $240+$400= $640
C. The two methods carries same cost levels, hence there is no differenciation between these two methods as per total cost. The firm can chose any of the method based on its coviniance. Hence, I can say that, these two methods carry same output, at the same total cost.
