Answer:
Explanation:
The only way to do this would be to plant more trees to replace the ones that have been harvested. Doing so takes time for the trees to grow and if the demand is too high your profit will still not be sustainable. Therefore, you would need to calculate the time it takes for a tree to fully grow and implement a daily limit of trees that can be harvested. That way your supply will continuously replenish enough to meet the demand but not be completely harvested. This ultimately leads to sustainable profit.
