Four whole numbers are each rounded to the nearest 10 , the sum of the four rounded numbers is 90 , what is the maximum possible sum of the original four numbers? HELP!!!?

Hi Lourdes Whats the highest number each number can go up to before it rounds up? Its +4 as each number will round up otherwise. So if the rounded up numbers were 10,20,30,30. They can go up to 14,24,34,34. So its 106. Hope that helps Mohammed
