The mean of this data is?
A. 21
B. 22
C. 28
D. 25
E. 9

Answer:
A
Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
here the sum is the total of the prices on the 5 bars
sum = 22 + 25 + 28 + 9 + 21 = $105
There are 5 different jackets, then count = 5
mean = [tex]\frac{105}{5}[/tex] = 21
The mean price of a jacket is $21
