A polar vortex causes the temperature to decrease from 3 degrees Celsius at 3:00 P. M. to -2 degrees Celsius at 4:00 P. M. The temperature continues to change by the same amount each hour until 8:00 P. M. Find the total change in temperature from 3:00 P. M. to 8:00 P. M.

By 8:00 P.M. the temperature was -22 degrees Celsius, so the temperature dropped down a total of 25 degrees from 3:00 P.M. to 8:00 P.M.

Step-by-step explanation:

i think the amount would be $140.62

this is a good question! i'll do some research and come back when i have the answer!
