1. What is the equilibrium price and quantity based on the following demand and supply equations? Solve by putting Qd = Qs Qd = 10-P Qs = P Quantity is given from 0 to 10 units on the x-axis. Price is given from $0.00 to $10.00 on the y-axis. Plot the Supply and Demand curves. 2. Now draw the Demand and Supply curves using the following Demand and Supply Schedule: Demand Schedule: QP 이 11 21 31 31 41 41 51 51 3. From number 2, draw a graph and call the equilibrium point (Point A). Illustrate on the graph what will happen to the Demand curve when consumers' income decreases? Supply Schedule: Q|P OF N 이 11 4. From number 2, draw another graph and call equilibrium Point A. Illustrate on the graph what will happen to the Supply curve when producers enter the market?

2. Christiaan can go hiking, or he can stay at home. Hiking would be fun if nothing bad happens, but there is a risk if he goes hiking that he will meet a bear (not fun) or get bitten by a snake (very not fun). Christiaan decides that if there is a 5% chance of meeting a bear and a 1% chance of getting bitten by a snake, he would prefer to go hiking rather than stay at home. However, if the chance of meeting a bear is 10% and the chance of a snake bite is 5%, he definitely would rather stay at home. then (a) Consider the utility function: U (stay home) = 25, U (hike no event) = 100, U (hike & snake) -1000, U (hike & bear) = -200. Does this utility function represent Christiaan's pref- erences? Explain. (b) Suppose that the utility function in (a) does represent Christiaan's preferences. Would Christiaan prefer to hike or stay home if the probability of meeting a bear is 6% and the probability of being bitten by a snake is 4%? Show your work.

At a company, 20 employees are making contributions for a retirement gift. Each of the 20 employees is choosing how many dollars to contribute from the interval [0,20]. The manager of these 20 employees announces that she will contribute dd dollars for every dollar that an employee contributes. The payoff to employee ii who makes contribution of xixi​ dollars is bi(1+d)xi−xi, where bi>0.bi​(1+d)xi​−xi​, where bi​>0. Assume that d=4d=4, bi=0.25bi​=0.25 for i=1,2,…,10i=1,2,…,10, andbi=0.5bi​=0.5 for i=11,12,…,20i=11,12,…,20 What is the best contribution level of any employee ii for i=1,2,…,10i=1,2,…,10.   At a company, 20 employees are making contributions for a retirement gift.
