Question
In a recent survey, a magazine reported that the preferred room temperature in the summer is 68°F. A
wall thermostat, like the ones shown below, tells a room's temperature in degrees Fahrenheit
Sarah's Upstairs Bedroom
Downstairs Bedroom
72°F
64°F
a.
Which bedroom is warmer than the recommended room temperature?
b.
Which bedroom is cooler than the recommended room temperature?
c. Sarah notices that her room's temperature is 4°F above the recommended temperature, and
the downstairs bedroom's temperature is 4°F below the recommended temperature. She
graphs 72 and 64 on a vertical number line and determines they are opposites. Is Sarah
correct? Explain.
d. After determining the relationship between the temperatures, Sarah now decides to represent
72°F as 4 and 64°F as -4 and graphs them on a vertical number line. Graph 4 and -4 on the
vertical number line on the right. Explain what zero represents in this situation.
