Question

Four friends all give each other presents.
The total cost of the presents is £80.52
Work out the mean cost of a present in pounds (£).​

Answer 1

Answer:

20.13

Step-by-step explanation:

Four friends all give each other presents.  The total cost of the presents is £80.52.

We need to find the mean cost of a present in pounds.

Mean = sum of observations/total no of observation

$M=\dfrac{80.52}{4}\\\\=20.13$

So, the mean cost of a present is equal to 20.13 .
