Quizplus · Accepted Answer

The Total Physical Product (TPP) of using the 5th unit of input can be determined by observing the pattern of output (Y) as the input (X) increases. Given that the Marginal Physical Product (MPP) of the 5th unit is 1, and the output at 4 units of input is 44 bu, adding the MPP of the 5th unit (1 bu) to the output at 4 units (44 bu) gives us a total output of 45 bu when 5 units of input are used.
