1. The problem statement, all variables and given/known data The following table shows the daily high tem- peratures for a week in May. Determine the change in temperature each day. Sun. 76◦ Mon. 72◦ Tues. 80◦ Wed. 75◦ Thurs. 75◦ Fri. 74◦ Sat. 78◦ Find the net change in temperature (the sum of all the temperature changes). 2. Relevant equations None 3. The attempt at a solution I know this seems easy, but I'm not getting the right answer: Sun. to Mon. = -4 degrees Mon to Tues. = 8 degrees Tues. to Wed. = -5 degrees Wed. to Thurs. = 0 degree Thurs. to Fri. = -1 degree Fri. to Sat. = 4 degrees Sat. to Sun. = -2 degrees Added them up and got: 0 degree Am I suppose to just add up the absolute value of the temperature changes?
