Question

The temperature outside changed from 82°F to 46°F over a period of six days. If the temperature changed by the same amount

each day, what was the daily temperature change?
A. 36°F
B. -6°F
C. 6°F
D. -36°F

Answer 1

B. -6

Explanation:

You know immediately that it will be negative, because the temp is going down.

To find the exact answer, start by finding the difference between the two temps

82-46 = 36

since its a six day period, divide 36 by 6

36/6 = 6

so, the answer is -6

Answer 2

to find the daily change, let’s first find the total change
46 – 82 = -36 °F

we have 6 days, so divide
-36 / 6 = -36 °F per day
