Based on the information provided in the screenshot below, I need to either use the Goal Seek or Solver tool in Excel to figure out the maximum amount Acme can pay for PHC if it wishes to maintain at least at 10% average return on beginning investment allowance. If someone could provide an explanation on how to use solver/goal seek to find the answer, I would be grateful!
