What is 6.805 rounded to the nearest whole number

The answer is 7.
To round a number to the nearest whole number, you use the decimal before the whole number. If the decimal in the tenth place is the number 5-9, it will go up a number. If it is below 5, it will stay the same, just without the decimal.
For example:
8.9 would be rounded to 9, because 0.9 is closer to the next whole number.
8.2 would be rounded to 8, because 0.2 is closer to the current whole number.

38 dollars is your answer.
