On Friday morning the temperature was 67°F. The temperature dropped 6°F and then rose 10°F. How much does the temperature need to rise or fall to return to the initial temperature of 67°F

To return to the initial temperature of 67°F after dropping 6°F and then rising 10°F, we need to calculate the total change and then reverse it.

The total change was a drop of 6°F followed by a rise of 10°F, so the net change was an increase of 4°F (10°F - 6°F = 4°F).

To return to the initial temperature of 67°F, the temperature would need to drop by 4°F (the net increase from the initial temperature) from the current temperature after the rise.

So the temperature would need to fall by 4°F (from 71°F to 67°F) in order to return to the initial temperature of 67°F.
