Question

I have posted the original question three different times, but have gotten several different answers ... usually with no work shown, or work that didn't particularly make sense from the way I was taught (so hard for me to understand). I am now trying this approach. Please check work, and if a mistake was made, show me what should have been done instead. I am desperate for help from someone who truly knows what they are doing.

Thank you ... 5 stars to answers with work/explanation. One star to answers only (fair warning).
