Answer:

The correct answer to the following question will be option C.

172.16.80.1-172.16.87.254

Explanation:

IP Address: IP Address stands for Internet Protocol Address, a unique numerical label allotted to every computer network that are connected to the network of the computer and communicate through the internet protocol.

  • An IP address can be separated by periods and having four numbers that are called Octet. Range of IP address can be from 0 to 255.
  • We have to keep the first 21 bits and start setting all from the 22nd bit on to 0 (zero).
  • To get the suitable and the correct range of the address, we add and subtract 1 from the given broadcast address i.e.,172.16.85.0/21.

So, option C is the right answer and no other option is usable according to the given explanation and the address given by the administrator.

ioda

Answer and explanation:

1. It asks for the total expenses for the month of March. So, let's add all of the March expenses up.

1,600 + 2,100 + 850 + 480 + 2,800 = $7,830 (which is the answer)

2. It asks what the highest expense for wages are. That would be $5,080. Out of all of the times that the wages have been paid, in April, it was the highest, at $5,080. So, $5,080 is the answer.

3. It asks how many items cost less than $1,000 in April. The only thing that cost less than $1,000 in April was the water because it only cost $370. So, the answer would be 1.

Hope this helps!
