Please don't take my answer as a reliable one, it could be incorrect.Plan A = 500+4nPlan B = 55nI suggest using the guess and check tactic.Say n = 10Then Plan A would equal to $540, Plan B would equal to $550.Say n = 11Then Plan A would equal to $544, Plan B would equal to $605When n is less or equal to 10, (it might be somewhere between 10 and 11 if the answer is a rational number) then Plan A would be the better choice.

Beyond 9.8, or 10+ hours
