Math question! show your work. over the past 4.85 days, mrs. smith found that the temperature outside had dropped a total of 22.2 degrees. find the average change in temperature each day.

Ok so what I did was 4×4.85=19.4 then I subtracted it from 22.2 the answer was 2.8 but .57 can still go into 2.8 so i multiplied
.57 × 4.85 which equals .0355 and then I realized that .007 can go into .0355 so I followed the same method and subtracted. the numbers to the sides are the ones i multiplied so I then added them and got 4.577

the answer is 4.58 or 4.6

Number nine is f(x)= 40x : ) hoped i ya
