Answer:

[tex]6 \le x \le 20[/tex]

Step-by-step explanation:

Call x the time that Kelly takes to change oil. If the wait time is charged to the customer, then, x must be less or equal than 20 minutes. If the fastest oil change that Kelly has ever done took 6 minutes, then, x will be greater or equal than 6. In mathematical terms, [tex]6 \le x \le 20[/tex]
