The range of temperatures is between 49 degrees and 64 degrees. An inequality would better to model this situation. The range of 7.5 degrees would be by itself on one side of the inequality symbol. Since this range would be added to or subtracted from the 56.5 degrees, we would use an absolute value sign on the other side of the equation.

Work Step by Step

56.5+7.5=64 56.5−7.5=49
