Work Shown:
Multiply across the rows to form a third column. Example: 9*90 = 810 in the first row.
The values in the third column add to 810+1440+1050 = 3300
Divide this over the total number of people which is 9+18+15 = 42
The mean is 3300/42 =78.571 approximately which rounds to 78.6

Step-by-step explanation:
To solve this problem we are going to use the simple interest formula:
where
is the sum of the <span>interest and the principal
</span>
is the principal
is the interest rate in decimal form
is the time in years
<span>
We know for our problem that </span>
,
, and
. Now, let
represents our interest rate. To express the interest rate in decimal form, we are going to divide the rate by 100%:
.
