Answer: Please refer to Explanation
Step-by-step explanation:
The Total Product of Labour curve is constructed by equating the quantity produced to labour. If every additional worker produces an additional unit of output then the Total product of labour curve will have a slope of 1 because every unit of labour leads to an additional unit of output.
Average Product will also be 1 because if each additional worker produces 1 extra then n workers is equal to n output. n divided by n will be one.
The Marginal Product of Labour is simply how much output is produced when an additional worker is added and the question already lists that as 1 so 1 is the answer.
