We can solve the equation M = 176 – 0.8A for A by substituting M = 135 and solving for A:
135 = 176 - 0.8A
0.8A = 176 - 135
0.8A = 41
A = 41 / 0.8
A ≈ 51.25
Therefore, at approximately 51 years of age, a person would have a recommended heart rate of 135 beats per minute during exercise. So the answer is 51 years.
During exercise, the recommended maximum heart rate in beats per minute is modeled by the formula M = 176 – 0.8A, where M is the maximum heart rate and A is the person’s age. Approximately, at what age would you have a recommended heart rate in beats per minute of 135?
25 years 39 years 51 years 53 years
