When rounding off the rule is you round off to the nearest 5.
17.2 would then be rounded of to 17. should it have been 17.5 you would then round up to the next 5 which would be 18
2.4 *60mins=144
25*60mins=1500
r=d/t
r= 1500/144
r=10.4
or
25/2.4= 10.4

Answer:
The smoothing constant alpha is 0.20 (Option a)
Step-by-step explanation:
To solve this problem, first we write the succession of the simple exponential smoothing:

Where s(t) is the forecast for period t, s(t-1) is the forecast for period (t-1), xt is the real demand for period t, and alpha is the smoothing constant.
All but the alpha constant are known
s(t)=109.2
s(t-2)=110
xt=110-4=106
Then, we can calculate alpha as:
