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 a expression to show the average change in the temperature of the city each week.
Part B: Simplify the expression and explain, using words, what your answer means.
Temp in city for weeks 1-4 = Starting temp - (20 deg C / 4 wk) * wk#
Temp in City for weeks 1-4 = starting temp - 5 deg c/wk * wk#
This shows the temperature in the city for weeks 1 2 3 4 given the original temperature of the city and whichever week you want to know from the starting point....week 1 week 2 week 3 week 4 .....
