Question

By noon, the temperature in Juneau had risen by 16ºF.
What was the temperature there at noon?

Answer 1

-17 degrees F

Explanation:

Assuming that the temperature in the chart is the temperature before noon, all we need to do to find the temperature at noon is to add 16 degrees Fahrenheit to the table value (since "risen by 16 degrees F" means to increase by 16 degrees, aka to add 16 degrees).

So,

-33 + 16 = -17

Answer 2

-17
Add -33+16 = -17
We get the -33 from the starting temperature
And the 16 because it increased 16 degrees
