That would be 59,000 because the 9 is in the ten thousandths place and you have to look to the number at the right to see if you should keep the number the same or go up one. In this case, it would stay the same
Let x = mileage 98 >= 35 + .21x Solving for x: 98 >= 35 + .21x 63 >= .21x 300 >= x . This says that if the total mileage is 300 miles or less he will be within his budget.
