C) fixed costs are more important to decision making in the long run than they are in the short run.
D) in the short run all resources are fixed, while in the long run all resources are variable.
28 The law of diminishing returns indicates that:
A) as extra units of a variable resource are added to a fixed resource, marginal product (i.e., the contribution to total output of another unit of variable input) will decline beyond some point.
