Choice B is the correct answer. Extend the patterns and compare.

1. Linear: $y = 10x + 10$ (add 10 each step).
2. Exponential: $y = 10(2)^x$ (multiply by 2 each step).
3. At $x=4$: Linear = $50$, Exponential = $160$, Difference = $110 > 100$ ✓
4. At $x=3$: Difference = $80 - 40 = 40 < 100$ ✗

💡 Strategic Tip: Exponential eventually dominates linear, but verify with calculation.

Choice A is incorrect because exponential exceeds by more than 100 before $x=5$. Choice C is incorrect because it exceeds by then, but not "first". Choice D is incorrect because at $x=3$, difference is only 40.
