Dr. cheeks tries to run at least 45 rotations on her hamster wheel each week. she has already run 6 rotations. which inequality shows how many more rotations, r, she would have to run to meet her weekly goal? a. r-6> 45 b. r-6> 45 c. r+6> 45 d. r+6< 45

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.
