On the following graph, use the green point (triangle symbol) to plot the annual total revenue when the market price is $40, $60, $80, $100, $120, $140, and $160 per bike. 6250 5820 Total Revenue 5390 4980 4530 4100 3670 3240 2810 2380 O 20 40 60 80 100 120 140 180 180 200 220 240 PRICE (Dollars per bike) According to the midpoint method, the price elasticity of demand between points A and B is approximately Suppose the price of bikes is currently $60 per bike, shown as point B on the initial graph. Because the demand between points A and B is , a $20-per-bike increase in price will lead to in total revenue per day. In general, in order for a price decrease to cause a decrease in total revenue, demand must be TOTAL REVENUE (Dollars)

A privately owned summer camp for youngsters has the following data for a 12-week session.(a) Develop the mathematical relationships for total cost and total revenue. (b) What is the total number of campers that will allow the camp to just break even? (c) What is the profit or loss for the 12-week session if the camp operates at 80% capacity? (d) What are marginal and average costs per camper at 80% capacity? (e) Would it be ethical to charge campers different rates depending on their family’s socioeconomic status? Identify and describe two points pro and two points con for such a policy.

Calculate price per unit of table if total revenue is $6600 and the output sold is 30 units

choices for 1 and 2 are its either "variable" or "fixed" please also do the rest of the questions and graph  thank you!
