A home in a Texas town has a standard-sized pool with dimensions of 4.2 m by 8.4 m and a depth of 1.8 m. The average temperature in the region during November is 20.0 oC. The temperature of the heated pool is set at 26.0 oC, and the pool is operated for 4.0 hours each day. The cost of heating the pool for that month is $250.00. How much money could be saved during that month if the pool temperature was lowered to 23.0 oC? (Assume that the swimming pool contains pure water.)
