7. In a simple model of predator (R)/prey (Y) populations, the populations at integer time increments are modeled as: Rt+1 = 0.5R: +0.25Y. Yt+1 = -0.5R: + 1.25Y For example, t might be integer) years. For predator (Ro) and prey (Yo) starting populations, a. C. What is the formula for the expected populations of predators and prey as too? b. If Ro = 25 and Yo = 100, what are the expected populations R. and Y-? Same question as b above, but with Ro = 10 and Yo = 200? d. In case c above, what are the expected populations after three time periods, R3 and Y3? Express your answers rounded to the nearest integer. 7. In a simple model of predator (R)/prey (Y) populations, the populations at integer time increments are modeled as: Rt+1 = 0.5R: +0.25Y.
