Garrett must inspect a bridge that goes over a river. he begins 18 feet above water level to inspect the lighting, descends 32 feet to inspect the base of the bridge underwater, then descends another 4 feet to check on the concrete anchoring the base. which best represents garrett’s position with respect to the water level? its not -10 (i got it wrong) –54 feet –30 feet –18 feet –10 feet
