C is the best answer, although an even better answer would be r+6 ≥ 45. We know that she runs at least 45 rotations each week and she's already completed 6 rotations. Since the value of r is how many more rotations she needs to run to meet her weekly quota of rotations, C is the best answer since she can run 45 rotations or more to meet her quota.

Answer: C. r+6>45

Step-by-step explanation:

Since, Dr. Cheeks tries to run at least 45 rotations on her hamster wheel each week.

If she runs r rotations then, for the value of r, $45\leq r$

Since, If she has already 6 rotations

Therefore total rotation she has = r+6

Thus, if $45\leq r$ ⇒ $45$

So, Option C is the correct option.
