Question

Can someone help me by looking at the picture above??

1. find the mean amount
charged = $ ?

Answer 1

Explanation:

To find the mean, you add all the numbers together then divide by the number of numbers.

Charge : 120+272+358+328+406+392+530+592+610=3608/9=400.888888 =400.89 dollars

Answer 2

Answer: 400.89

=======================================================

Work Shown:

To find the average price, we will add up the 9 values in column 2 to get

120+272+358+328+406+392+530+592+610 = 3,608

Then divide that total by 9 since there are 9 values we added up

We get the average to be (3,608)/9 = 400.888 which is approximate. This rounds to 400.89

Side note: It's a bit strange how your teacher mentions "charge in pounds" but then uses a dollar sign.
