State the practical range using interval notation for the scenario: the amount of sand forming a dune decreases from 100000 kilograms. It decreases by half every year,forever,but it never decreases to 0 kilograms.

The answer is 20^3 because by the end of 6 hours the number of bacteria has doubled every two hours meaning that after the first two hours you have 2000, then another 2000 after two hours, then 4000 after the next two hours, ans finally at the end of 6 hours, you have 8000 bacteria aka 20^3
