Answer: 18
Step-by-step explanation: If you add all 3 numbers, you will get 17.58
Now to round it to the nearest whole numbers, look at the 2 whole numbers nearest to it. 17 or 18. Anything .49 or lower will round down. Anything .50 or higher will round up. So if it was 17.49 it would round round to 17. This is 17.58 so it will round up to 18.
