Answer: ≈ 194.3
Step-by-step explanation: So, first we need to find out how many pounds she lost alone in 11 1/2 days. So, we take the full amount of 11.5 (which is 11) and multiply it by 0.5. That'd be 5.5 or 5.50. Now, we need to find half of 0.5. That'd be 0.25. Now, we add 0.25 to 5.5. That'd be 5.75. So in 11 1/2 days, Cindy lost 5.75. Although, now it asks how much weighs after she lost 5.75 lbs. So, we subtract the 200 lbs (starting weight) from the pounds lost during the 11 1/2 days. That'd be 194.25. So, therefore she lost about 194.3 lbs. I hope this helped!
