Answer:
Ari has 14 pennies.
Step-by-step explanation:
Number Value Total value
Pennies p $0.01 0.01p
Nickels (22 - p) $0.05 $(22 - p)0.05

-0.04p = -0.56
p = 
p = 14

<h3>What is a mean?</h3>
Your information is incomplete. Therefore, an overview will be given. It should be noted that a mean simply means the average of a set of numbers that are given.
For example, if we have the following numbers:
3, 9, 4, 1, and 3. The mean will be:
= (3 + 9 + 4 + 1 + 3)/5
= 4
The mean absolute deviation is the average distance between the data points and the mean.
