If a manufacturer of electronic devices invests $620,000 in equipment for making compact piezoelectric accelerometers for general purpose vibration measurement, estimate the rate of return from revenue of $220,000 per year for 10 years and $80,000 in salvage value from the used equipment sale in year 10. Which is the correct equation to calculate the rate of return?

In the short-run, marginal costs are equal to the change in variable costs as output changes. ( mc = change in variable cost / change in quantity) assume that capital is fixed in the short-run. (a) start with the equation for marginal cost and derive an equation that relates marginal cost of production to the cost and productivity of labor. (b) draw a standard looking short-run marginal cost curve and use the equation you derived to explain its shape.
