Final answer:
The coach would use the inequalities 10x + 5y ≥ 5000, x ≥ 0, and y ≥ 0 to create the graph.
Step-by-step explanation:
The coach would use the following inequalities to create the graph:
10x + 5y ≥ 5000
where x represents the number of premium seats sold and y represents the number of regular seats sold. This inequality ensures that the total revenue from premium and regular seats combined is at least $5000.
x ≥ 0
This inequality represents the constraint that the number of premium seats sold cannot be negative.
y ≥ 0
This inequality represents the constraint that the number of regular seats sold cannot be negative.
