The shopping channel shipped 467023 packages last year. what is a reasonable estimate of the number of packages shipped?

500,000 packages. You can round. If the digit before the number you are rounding to is less than 4, you keep it the same and make all the numbers following 0. If it is 5 or above, you can make the number that comes before it (in this case the 4) into a (in this case 5).

Well it could be 500,000; 470,000; 467; 000; or 467,020
