A cook removes a package of food from a freezer and begins to defrost the package. • The initial temperature of the package of food is -15 degrees F. • At noon, the temperature of the package of food has increased to 35 degrees F. What is the total change in temperature, in degrees Fahrenheit, for the package of food?
The total change in temperature for the package of food is the difference between the final temperature and the initial temperature.
Final temperature = 35 degrees F
Initial temperature = -15 degrees F
Total change in temperature = Final temperature - Initial temperature
Total change in temperature = 35 degrees F - (-15 degrees F)
Total change in temperature = 35 degrees F + 15 degrees F
Total change in temperature = 50 degrees F
Therefore, the total change in temperature for the package of food is 50 degrees Fahrenheit.
