F=110+0.12d
A travel agent arranges trips for climbing Mount Kilimanjaro. For each trip, the agent charges an initial fee in addition to a certain amount for each vertical meter climbed. The equation shown above gives the total fee, FF, in dollars, for a trip whose vertical distance climbed is dd meters.
