At 2pm the temperature is 22 degrees, by 4am it is negative 7 degrees. We think the answer in the change of temperature is 22 degrees am I right?
No.
When the temperature got to 0, the change was 22 degrees. Now, subtract 7 degrees from 0 to find the total change in temperature.
Ok, I came up with 29
Yes. It dropped 29 degrees.
To find the change in temperature, you need to subtract the initial temperature from the final temperature.
In this case, the initial temperature is 22 degrees and the final temperature is -7 degrees. To calculate the change in temperature, you subtract -7 degrees from 22 degrees:
Change in temperature = Final temperature - Initial temperature
= -7 degrees - 22 degrees
= -29 degrees.
So, the change in temperature is -29 degrees, not 22 degrees.
