The temperature of a city changed by −12 degrees Celsius over a 2-week period. The temperature changed by the same amount each week. Part A: Write an expression to show the average change in the temperature of the city each week. (5 points)

Part B: Simplify the expression and explain, using words, what your answer means. (5 points)

Part A) -12/2

Part B) The expression would be -6. My answer means that the temperature dropped by 6 degrees Celsius every week and .85 degrees Celsius per day.

Step-by-step explanation:

To do Part A, you need to divide -12 by two to figure out how much it dropped each week. We divide by two because there are two weeks. The way we get how much it drops each day is we divide how much it dropped a week by 7 since there are 7 days in a week. :)
