Julia shipped 6 packages. The lightest one weighed 4.2 pounds, and the heaviest one weighed 11.7 pounds. Which range is a reasonable total weight of the 6 packages combined?

Answer 1

The range is the largest value minus the smallest value. The largest value is 11.7. The smallest value is 4.2. The range is 11.7 - 4.2 = 7.5 pounds.
