1. Suppose you belong to a tennis club that has a monthly fee of $100 and a charge of $5 per hour to play. Prepare a table and draw a curve to show the relationship between the hours of tennis (on the horizontoal axis) and the monthly club bill (on the vertical axis). For the table and graph use 5, 10, 15, and 20 hours of tennis.Find the slope of the curve per .The slope of the curve is per .Suppose you start with 10 hours of tennis and then decide to increase your tennis time by 3 hours. On your curve show the inital point and the new point. By how much will your monthly biill increase?Suppose you start with 10 hours and then decide to spend an additional $30 on tennis. On your curve, show the initial point and the new point . How many additional hours can you get?2 A graph shows the relationship between the number of Frisbees produced and the cost of production. The vertical intercept is $, and the slope of the curve is $ per Frisbee. Point b shows that the cost of producing Frisbees is $.

Prepare a table and draw a curve to show the relationship between the number of CDs(on the horizontal axis) and movies (on the vertical axis) you can afford to pay.The slope of the curve is per .You manage Gofer Delivery Service. You rent a truck for $50 per day and each delivery takes an hour of labor time. The hourly wage is $8. Draw a curve showing the relationship between the number of deliveries (on the horizontal axis) and your total cost (on the vertical axis). Draw the curve for between 0 and 20 deliveries.The slope of the cost curve is per .To draw the curve, what variables are held fixed? A change in wold cause a movement upward along the curve.Changes in would cause the entire curve to shift upward.A change in a variable measured on an axis of a graph casues movement a curve, while a change in a relevant variable is not measured on an axis the curve.
