Differentiate between Fixed and Variable Costs?

Graph the following:  Average Total Cost curve and Average Variable Cost curve with proper positioning

Why do most fixed costs become variable costs in the long run?

Is fixed cost always smaller than total cost ?

Draw a graph with the quantity of money on the horizontal axis and the interest rate on the vertical axis. Initially, the money supply curve is vertical because its determined by the Fed. The demand for money curve slopes downward, indicating the negative relationship between the interest rate and the quantity of money demanded.

If the marginal cost is increasing, do you know whether average variable cost is increasing or decreasing? Explain.
