1 . The following table gives the price and demand for a certain brand of calculator. Demand in hundreds Price in dollars 4 125 9 119 15 108 22 97 25 91 32 80 a Find the linear demand function using regression in Excel or with your calculator. b. Report and interpret the slope of your demand function. C. Using your function find the price when the demand is zero. d. Using your function find the demand when the price is $100'algebraically. e . A supplier is willing to supply 800 calculators when the price is $36.80 and is willing to supply 1500 calculators when the price is $51.50. If the supply function is linear, find the supply function algebraically letting x be hundreds of calculators. f. Find the equilibrium point algebraically using your demand and supply functions. Interpret the meaning of this point in a sentence. g. Graph the supply and demand equations on the same set of axis with your graphing calculator or graphing utility. Copy the graph into your paper. Make sure you include a title, the scale, label the axes, and clearly label each function with the equation. h. Label the equilibrium point on your graph. i. Suppose the price of the calculator is now $40, predict what will happen to the price and explain why using supply and demand
