A parasailer 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 parasailer's chute catches less air and dips 25
meters. She must 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.
