The short-period supply price, on the other hand, is equal to the marginal prime cost.

因此，杂货的主要成本在这两个地方是相同的，它们在收取最低利润的地方是最便宜的。

In his capacity as a producer deciding whether or not to use the equipment, prime cost and gross profit, as defined above, are the significant concepts.

Moreover, if equipment is non-homogeneous and some part of it involves a greater prime cost per unit of output, we shall have increasing marginal prime costs over and above any increase due to increasing labour-costs.

此外，如果设备是非同质的，并且其中的某些部分涉及每单位产出的更高主要成本，那么我们将增加边际主要成本，这超过了由于劳动力成本增加而导致的任何增加。

Thus the long-period supply price is equal to the sum of the prime cost, the supplementary cost, the risk cost and the interest cost, into which several components it can be analysed.

因此，长期供应价格等于主要成本、补充成本、风险成本和利息成本之和， 可以分解为几个组成部分。

The prime cost of bread and butchers' meat is greater in the great town than in the country village; and though the profit is less, therefore they are not always cheaper there, but often equally cheap.

The level of output, at which marginal prime cost is exactly equal to the sum of the average prime and supplementary costs, has a special importance, because it is the point at which the entrepreneur's trading account breaks even.

边际主要成本恰好等于平均主要成本和补充成本之和的产出水平具有特殊的重要性，因为这是企业家交易账户收支平衡的点。
