Consider a market for electric vehicles with demand given by D(p)=100-p. Xiaoniu is a producer in this

market, facing a cost function given by c(y)=20y.

b. Suppose in addition to Xiaoniu, another firm, Aima, also produces electric vehicles. The cost function

for Aima is given by c(y)=30y. If Xiaoniu and Aima simultaneously set output levels, how many vehicles

will be produced by each firm in equilibrium? What is the equilibrium price?
