Choice A is the correct answer. Find the pattern and sum.

1. Pattern: $2, 8, 32, ...$ means multiply by 4 each hour: $A(h) = 2(4)^{h-1}$.
2. Calculate Each Hour:
   • Hour 1: 2
   • Hour 2: 8
   • Hour 3: 32
   • Hour 4: 128
   • Hour 5: 512
3. Total: $2 + 8 + 32 + 128 + 512 = 682$ acres.

💡 Strategic Tip: Sum a geometric series: $a(\frac{r^n - 1}{r - 1})$ or calculate each term.

Choice B is incorrect because this is just hour 5, not the total. Choice C is incorrect because this is the sum of only hours 1-4. Choice D is incorrect because this would be hour 6.
