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 $2,500 for setup costs and $3.00 to administer each test.
• Write an expression that gives the total cost to test x animals.
• You can find the average cost per animal by dividing total costs by number of animals. Write the expression that gives the average cost per animal.
• Find the average cost per animal for 10 animals, 100 animals, and 1,000 animals.
• As the number of animals tested increases, what happens to the average cost to test the animals? Would the average cost ever fall below $3.00? If so, identify a value that supports your answer. If not, explain how you know.
• How many animals should be tested for the average cost to be $5.00 per animal?
