Can someone please help me with my final? i cant answer these last questions. Please help me 
1)Suppose that the supply and demand curves are given by q=1000-25p and q= 30p +10 respectively. Find the equilibrium point. Find the consumer surplus and the producer surplus.
2)( Continuning # 1) suppose that a 5%sales tax is imposed on the consumer. Find the new supply and demand equations . Find the new equilibrium. How much tax is paid on each unit? How much by the consumer, how much by the producer? How much tax does the government collect? Find the consumer surplus and the producer surplus.
3) Whooping cough was thought to be nearly eradicated. It is known that the vaccination wears off, leading to an increase in the number of cases, from 1248 in 1981 to 18,957 in 2004. With t representing time and w representing the of whooping cough cases find an exponential function that models this data. What does the model give as the average annual percent growth rate of the number of cases? What is the doubling time for your model? The Arizona Daily Star reports that the case doubled between 2000 and 2004, does this fit your model, why? If your work for a drug company that has estimated that the cost of producing more vaccine is prohibitive unless there are 100,000 cases, what year might expect to begin distribution?
