Since I do not have answer choices, I can conclude things that may or may not be an answer choice. Just from the problem, you can tell that Marie lost more weight, because 175 -150 = 25, while 190 - 180 = 10. Indirectly, you can say that she might have worked out more, or changed her diet, although that would merely be an inference. If you have answer choices please let me know and I can answer more. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine).
