7. People living in Florida sometimes find that the water in their swimming pools becomes uncomfortably warm during the summer months. This situation can be rectified
by adding ice cubes to the pool. The following authentic formula can be used to
determine the approximate number (N) of 5-pound bags of ice required to reduce the
temperature of a pool by D degrees Fahrenheit if the volume of the pool is V cubic feet:
N = 0.06125DV. Gomer’s pool is roughly rectangular in shape, with a length of 50 feet,
width of 20 feet and average depth of 5 feet. How many bags of ice will be required to
reduce the temperature of the pool by 10°?

PLEASE EXPLAIN HOW!
