Marginal product is defined as the incremental change in output that occurs due to a change in the input signals.
It is calculated on two steps: 1- Find the change that occurred to the outputs 2- Divide this change by the additional inputs
For the problem we have here: Step 1: old output = 100 dumplings new output = 175 dumplings change that occurred = 175 - 100 = 75 Step 2: This change occurred as a result of adding 1 worker Therefore: marginal product = 75/1 = 75
