A biology department was called in to help with the jellyfish problem in Lake Superior The biology department decided to introduce a new species of aquatic squirrels to help deal with the growing jellyfish population. If the jellyfish population (in the presence of aquatic squirrels) can be modeled by P = 0.75t + 75 and the aquatic squirrel population can be modeled by P = 0.5t + 3 where t is the number of weeks since the introduction of the aquatic squirrels. (a) Write a question involving the above scenario which would require the problem-solver to solve the following system of linear equations: P = 0.75t + 75, P = 0.5t + 3 (b) According to the population models for the jellyfish and aquatic squirrels, when do the models predict that the jellyfish will become extinct? (When will the aquatic squirrels achieve victory over the invasive jellyfish?) Explain how you know.
