Diminishing returns to labour? Negative returns to labour? c. Over what range of labour input is marginal product greater than average product? What is happening to average product as employment increases over this range? d. Over what range of labour input is marginal product smaller than average product? What is happening to average product as employment increases over this range? e. Assuming that the price of each repair is $50, add another two columns and calculate the MRPL
