190 / 5 = 38
38 * 31 = 1178
1178 * 4 = 4712
= $47.12
Increase- to be more significant in value, to be of more worth, to have a larger quantity.
Basically, if I said I added 2 to 5, that would be an increase.
2+5=7 7 is bigger than 5.
If I subtracted 2 from 5, that would make a decrease in value.
5-2=3 3 is smaller than 5.
I hope this helps!

Answer:
1877 computer users
Step-by-step explanation:
We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.
We apply the following formula:
n = [z * sd / E] ^ 2
replacing:
n = [1.96 * 221/10] ^ 2
n = 1876.27
that is, the minimum sample size is 1877
