a parasailor is attached by a cable to a boat and towed so that the parachute she is wearing catches air and raises her into the air. When the boat slows down to turn back toward the beach, the parasailor's chute catches less air and dips 25 meters. She might descend another 45 meters to return to the boat. Write and solve a subtraction equation to find her original height above the boat before the turn.
