Skill Level I: You are an American exchange student planning to study in Florence, Italy, during the winter term. In preparation for your trip, you consult the Italian school's Web site to find out what the temperature is likely to be. However, the daily weather is given in the Celsius scale. Use the table to find a way to convert temperatures from the Celsius to the Fahrenheit scale.
Skill Level II: Find a relationship that will allow you to go from a Fahrenheit measurement to a Celsius measurement in two ways:
1. By graphing the data in a chart drawn in Skill Level I
2. By taking the relationship that you found in Skill Level I and algebraically manipulating it so that TC is isolated.
