Mean Absolute Deviation is a quantity of measurement that gives you an idea how far, on average, are the data points deviating from the mean. Its equation is
MAD = ∑|x - μ| / N, where
x is a single data point
μ is the mean of the data set
N is the total number of data points
Suppose, a data set consist of the following: 4, 7, 5, 9, 6, 7, 7, 4. Let's solve first for the mean:
μ = (4+7+5+9+6+7+7+4)/8 = 6.125
Then, the MAD is equal to:
MAD = (|4 - 6.125| + |7 - 6.125| +|5 - 6.125| +|9 - 6.125| +|6 - 6.125| +|7 - 6.125| +|7 - 6.125| +|4 - 6.125|) ÷ 8
MAD = 11/8
MAD = 1.375

Hello!
First of all let's divide and find how much each calculator cost.
95.2/14=$6.80
Now we will subtract from 24.
24-6.8= 17.2
Mr. Morris has $17.2 left to spend on each student.
I hope this helps!
