On February 18, from 9 a.m. until 2 p.m., the temperature rose from -14°F to 36°F. What was the total increase in temperature during this time period?

Answer 1

Mila Anderson

The increase is #50^oF#. See explanation.

To calculate the increase you have to subtract the lower value from the higher one.

Here it is:

#36-(-14)#

To subtract a negative number you add the opposite number:

#36-(-14)=36+14=50#

To find the total increase in temperature during the time period from 9 a.m. to 2 p.m. on February 18, subtract the initial temperature from the final temperature.

Final temperature = 36°F Initial temperature = -14°F

Total increase in temperature = Final temperature - Initial temperature = 36°F - (-14°F) = 36°F + 14°F = 50°F

Therefore, the total increase in temperature during this time period was 50°F.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
