Suppose there are 20 people in a room and the mean amount of cash held by these 20 people is $11.50 per person. If two people enter the room carrying $28.00 and $10.00 respectively, what does the mean amount of cash in the room become?

Answers

The mean amount of cash in the room become 12.18 dollars.

It is required to find the mean.

What is mean?

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Mean = (Sum of all the observations/Total number of observations).

Given that:

There are 20 people with a mean of 11.5 we multiply that:

20×11.5=230

We add the 38 dollars that the new two people are bringing in:

230+38=268

And we divide that by the new total of people by 22, we get

268/22= 12.18

Therefore, the mean amount of cash in the room become 12.18 dollars.
