Guy please help me out so this is the question 3.  Last Sunday, the temperature at 8:00 a.m. was -3०C.  Between 8:00 a.m and 1:00 p.m., the temperature rose by 5०C.  By 6:00 p.m. the temperature was 2०C colder than it was at 1:00p.m.  Then, the temperature dropped 3०C each hour between 6:00 p.m. to 10:00 p.m.  What was the temperature at 10:00 p.m.? I got the answer -1 is that correct?​
