If labor is a variable input in production, the law of diminishing marginal returns
implies that in the short run
A) labor’s marginal product is constant.
B) labor’s marginal product decreases after a certain point.
C) total product is negative.
D) total product is negative after a certain point has been reached.
If we know average total cost and the amount of output, then we can always calculate
total cost by
A) adding average total cost and the amount of output.
B) subtracting the amount of output from average total cost.
C) multiplying average total cost by the amount of output.
D) dividing average total cost by the amount of output.
