Doctors have two methods of calculating maximum heart rate. with the first method, maximum heart rate, y, in beats per minute is y = 220 − x, where x is the person's age. maximum heart rate with the second method is shown in the table.
age, x 20 30 40 50 60
heart rate (bpm), y 194 187 180 173 166
which method gives the greater maximum heart rate for a 90−year-old?
