The law of diminishing marginal returns

Question

The law of diminishing marginal returns holds that the:   a. total product of any variable factor of production will eventually decline, all other things unchanged.   b. marginal product of any variable factor of production will at some point decline, because it will eventually become burdened with an excess and overwhelming abundance of other factors in the long run   c. marginal product of any variable factor of production will eventually decline, assuming the quantities of other factors of production are given.   d. total product can only increase so long, because factors of production eventually become tired or wear out. ts of Producing Bagels (cents)   Quantity of Bagels Total Variable Costs Total Fixed Cost per period 0 0 10 1 20   2 30   3 35   4 45   5 60   6 80   7 105   8 135   the total cost of producing 6 bagels is equal to $________ and the marginal cost of the 6th bagel is  $__________.   a. 0.20; 0.20   b. 0.80,0.20   c. 0.20;0.90   d. 0.90; 0.20
