Choice C is the correct answer. Substitute $t=3$ into the equation.

1. Substitute: Replace $t$ with 3 in the function: $V(3) = 100(2)^3$.
2. Exponentiate: Calculate $2^3 = 2 \times 2 \times 2 = 8$.
3. Multiply: $100 \times 8 = 800$.

💡 Strategic Tip: Follow the order of operations (PEMDAS). Exponents first, then multiplication.

Choice A is incorrect because it calculates $100 \times 2$ first (linear thinking). Choice B is incorrect because it calculates $100 \times 2 \times 3$ (linear growth). Choice D is incorrect because it miscalculates $2^3$ as 10 or adds.
