Explanation:
The given situation can be represented by the following system of inequalities:
x ≥ 4 (Spending at least 4 hours at the zoo)
y > 2 (Spending more than 2 hours at the fair)
x + y ≤ 8 (Total time spent at the zoo and fair cannot exceed 8 hours)
Therefore, the system that represents this situation is:
x ≥ 4
y > 2
x + y ≤ 8
