Answer:
The required inequality is: 
The graph is shown in figure.
Step-by-step explanation:
Consider the provided information.
Chad will need at least 24 minutes to complete the 5K race. However, he wants to finish in under 30 minutes.
Let the time taken to finish the race is represented by x.
Chad need at least 24 minutes and he wants to finish in under 30 minutes.
Thus, the required inequality is:

Now draw the graph of the inequality.
Use a dot or close circle to represents ≤ and use an open circle to represent <.
The value of x is greater than or equal to 24 but less than 30, Thus the required graph is shown in figure.
The answer is number 4. No, he is not correct and the correct answer is: 10r + 10
