During the synthesis stage of the cell cycle, a cell makes (replicates its own) DNA.
Economic profits equals total revenues minus the sum of explicit costs and implicit costs. Since explicit costs are already subtracted when arriving at the accounting profit, we can find economic profit by subtracting the implicit costs from the accounting profit.
The Costs of Production. In economic terms, the true cost of something is what one has to give up in order to get it. This includes explicit monetary costs of course, but it also includes implicit non-monetary costs such as the cost of one's time, effort, and foregone alternatives.or example, if the total cost of producing 3 units of output is $15 and the total cost of producing 4 units of output is $17, the marginal cost of the 4th unit (or the marginal cost associated with going from 3 to 4 units) is just ($17-$15)/(4-3) = $2.
