$42.50 divided by 4 is 10.625
Than rounding that up to the nearest hundreds which is the number 2, the total is $10.63.
The answer is 8.
half of 16 is 8
For this case we have the following functions:

We must find the product of the functions:

We apply distributive property:

Finally, the product of the functions is:

Answer:

<h3>
Answer: 78.6</h3>
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
