Cutting Timber. A stand of fir trees occupies 60 acres, with an average density of 200 trees per 20 acres. A forester estimates that each tree will yield 400 board-feet of lumber. Estimate the yield of the stand in board-feet if one-tenth of the trees are cut.

On the following graph, use the green point (triangle symbol) to plot the weekly total revenue when the market price is $50, $75, $100, $125, $150, $175, and $200 per scooter. TOTAL REVENUE (Dollars) 2610 2430 2250 2070 1800 1710 1530 1350 1170 990 0 25 50 75 100 125 150 175 200 225 250 275 300 325 PRICE (Dollars per scooter) Total Revenue ? According to the midpoint method, the price elasticity of demand between points A and B is approximately 0.69 Suppose the price of scooters is currently $125 per scooter, shown as point A on the initial graph. Because the demand between points A and B is Inelastica $25-per-scooter decrease in price will lead to a decrease in total revenue per week. In general, in order for a price decrease to cause a decrease in total revenue, demand must be Inelastic

A contractor purchases a backhoe for $37, 300. Fuel and standard maintenance cost $5.95 per hour, and the operator is paid $12.03 per hour. a. Write a cost function for the cost C(z) of operating the backhoe for hours. Be sure to include the purchase price in the cost function. Cost function: C(z) = dollars b. If customers pay $27.77 per hour for the contractor's backhoe service, write the revenue function R(z) for the amount of revenue gained from a hours of use. Revenue function: R(x) = I c. Write the profit function P(x) for the amount of profit gained from a hours of use. Profit function: P(x) = dollars dollars d. How many hours must the backhoe be used in order to break even (assume that part of an hour counts as a whole hour)? In order for the contractor to break even, customers need to pay to use the backhoe for a total of hours.
