(01.05 MC)The temperature of a city changed by −20 degrees Celsius over a 4-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)

Step-by-step explanation:

po

4 weeks change = -20

1 week change = -5

If x is the temperature at the start of the week:

A: (4x-20)/4

B: Change per week = x-5 This means that the temperature goes down by 5 degrees per week, with x being the temperature at the start of the week.
