The heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) according to the equation |x – 72.5| = 4. What are the minimum and maximum temperatures in the house?

An absolute value of 4 means the temperature is 4°F away from 72.5°F in either direction. Subtracting and adding 4 gives 72.5 − 4 = 68.5°F and 72.5 + 4 = 76.5°F. The minimum and maximum temperatures are 68.5°F and 76.5°F, choice B.
