you pull out the plug from the bathtub. after 30 seconds, there are 14 gallons of water left in the tub. one minute after you pull the plug, there are 9 gallons left.
how many gallons of water were in the tub initially, that is before the plug was pulled?
how many gallons of water were still in the tub 45 seconds after the plug was pulled.
