Answer:
The value for the original mean = 32
Step-by-step explanation:
Here, we want to calculate the original value of the mean.
Let the number of samples be n
Mathematically;
mean = Total value/n
Now, we added 8 to each of values; total value added = 8 * n = 8n
Now, for the new mean of 40; we have
(Total value + 8n)/n = 40
Total value + 8n = 40n
Total value = 40n -8n
Total value = 32n
kindly recall from the beginning of the solution;
mean = Total value/n
mean = 32n/n
mean = 32
So the original value of the mean is 32

Answer:
8 Nickels
Step-by-step explanation:
Since a Nickel is worth 5 cents ($0.05)
And a Quarter is worth 25 ($0.25)
and theres 22 coins
8 of those coins would be nickels which would mean we add 8 nickels up
8 x 0.05 = 0.4
then we add the quarters up
14 x 0.25 = 3.5
3.5 + 0.4 = $3.90
