Doctors use the term maximum heart rate (MHR) when referring to the quantity found by starting with 220 beats per minute and subtracting 1 beat per minute for each year of a person's age. Doctors recommend exercising 3 or 4 times each week for at least 20 minutes with your heart rate increased from its resting heart rate (RHR) to its training heart rate (THR), where

THR = RHR + .65(MHR - RHR)
What is closest to the THR of a 43-year-old person whose RHR is 54 beats per minute?

You can put this solution on YOUR website!
We are given
THR = RHR + .65(MHR - RHR)
we know MHR = 220 - 43 = 177
RHR = 54
then
THR = 54 + .65(177 - 54)
THR = 54 + 79.95
THR = 133.95 = 134
