Answer :
To determine the estimated maximum heart rate, we use the well-known formula:
$$
\text{Maximum Heart Rate} = 220 - \text{age}
$$
Here's the step-by-step reasoning:
1. We are given a list of four formulas. The goal is to identify which one matches the above formula.
2. Looking at the options:
- Option A: $200 - \text{age}$
- Option B: $220 - \text{age}$
- Option C: $220 + \text{age}$
- Option D: $200 + \text{age}$
3. Notice that Option B exactly matches the formula we recognize, which is $220 - \text{age}$.
4. Therefore, the estimated maximum heart rate is given by Option B.
Thus, the correct answer is Option B (or 2, corresponding to "$220-\text{your age}$").
$$
\text{Maximum Heart Rate} = 220 - \text{age}
$$
