Answer :
To determine your estimated maximum heart rate, we use the formula
$$
\text{Maximum Heart Rate} = 220 - \text{Age}.
$$
Here's a step-by-step explanation:
1. The formula states that you start at 220 and subtract your age. This gives the estimated maximum number of beats per minute your heart can handle during exercise.
2. Reviewing the options provided:
- Option A: \(220 - \text{your age}\)
- Option B: \(200 + \text{your age}\)
- Option C: \(220 + \text{your age}\)
- Option D: \(200 - \text{your age}\)
3. Since the formula is \(220 - \text{Age}\), the correct expression matching this calculation is in Option A.
Thus, the estimated maximum heart rate is determined by the formula \(220 - \text{your age}\), and the correct answer is Option A.
