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 125? (1 point)
52 years
64 years
67 years*
70 years
M = 176 – 0.8A
125 = 176 - 0.8A
0.8A = 51
A = 51 / 0.8
A = ?
