Give the step-by-step reasoning process and then the final answer. A gecko lays 30 eggs per year. 20 percent of them are infertile, and a third of the remaining eggs will not hatch due to calcification issues. How many eggs actually hatch?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Infertile:30(.20) = 6. 30 - 6 = 24 eggs remain. Calcification Issues:24(1 / 3) = 8. 24 - 8 = 16 eggs that will hatch.
The final answer: 16.
