2. Biologists want to set up a station to test alligators in the lake for West Nile Virus. Suppose that the costs for such a station are $3000 for setup costs and $2.00 to administer each test. e. How many animals should be tested for the average cost to be $5.00 per animal?

avgcost*n=3000+2n
solve for n.
