ECN437 Exercise 1 Due Monday 1/30 Suppose that on a Saturday night there are 20 people who'd each like pizza.  Each person's willingness to pay for pizza is given by the equation  W2Pi=10-Qi, where W2Pi is the maximum amount person i is willing to  pay for pizza number Qi (eg, the person is willing to pay $9 for the first  pizza, $8 for the second, etc.). There are 10 stores that will deliver a pizza.  Each store has the following total cost equation: TCj=16+Qj*Qj, where Qj  is the number of pizzas produced by firm j and Qj*Qj means Qj squared.
