Multiple Choice

Suppose that an experiment that involves learning in animals requires placing white mice and rabbits into separate, controlled environments, environment I and environment II. The maximum amount of time available in environment I is 300 minutes, and the maximum amount of time available in environment II is 400 minutes. The white mice must spend 20 minutes in environment I and 35 minutes in environment II, and the rabbits must spend 45 minutes in environment I and 50 minutes in environment II. Let x represent number of white mice and y represent number of rabbits. Determine the system of inequalities that describes the constraints on the number of each type of animal used in the experiment. Then graph the solution of the system of inequalities. ​
