Question

On a given morning the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F?

A) Fall 8°F
B) Fall 3°F
C) Rise 8°F
D) Rise 5°F

Answer 1

B. Fall 3°F is your answer.

Answer 2

The temp starts at 71 degrees then drops 5 degrees

71 - 5 = 66 degrees

then it rises 8 degrees

66 + 8 = 74 degrees

How much does the temp have to rise or fall to get back to 71...

74 - 71 = 3 degrees

It has to fall 3 degrees F. Answer B.
