snow days

4

Step-by-step explanation:

The mean (or average) is the sum of all snow days divided by number of districts.

5 = (4 + 8 + 3 + 6 + x) / 5

25 = 21 + x

x = 4

The answer is 4.

Multiply the mean and the number of districts for the total.

Then add up all the number of snow days.

Lastly, subtract the total and the number of snow days.

(mean)5 x 5(districts) = 25

4+8+3+6= 21

25-21= 4
