Gettin' shmoopy with it...

The arithmetic mean of p numbers is k.

00:08

Twice the sum of those numbers is 240. What is p?

00:12

And here are the potential answers...

00:16

Okay, so we're on the lookout for p...

00:21

We can find averages by taking the sum of numbers and

00:24

dividing the sum by the... number of numbers.

00:30

In this case, we know that the mean, or k,

00:34

equals the sum of the numbers divided by the number of numbers (p).

00:39

Since we know that twice the sum is 240, the actual sum is 120.

00:45

Our equation becomes k equals 120 over p.

00:48

Because we want to find p, not k, we just need to rework the

00:52

equation to isolate p from the rest of it.

00:55

And we get p equals 120 over k.

00:58

The answer is B.
