Answers 86. The water level in a retention pond started at 5 ft (60 in.) and decreased at a rate of 2 in./day during a 14- day drought. A tropical depression moved through at the beginning of the 15th day and produced rain at an average rate of 2.5 in./day for 5 days. Write a piecewise-defined function to model the water level L(x) (in inches) as a function of the number of days y since the beginning of the drought.
