###### Exercise58

Target heart rate for moderate exercise is $$50\%$$ to $$70\%$$ of maximum heart rate. If we want to represent a certain percent of an individual’s maximum heart rate, we’d use the formula

\begin{equation*} \text{rate}=p(220-a) \end{equation*}

where $$p$$ is the percent, and $$a$$ is age in years.

Determine the target heart rate at $$53\%$$ level for someone who is $$22$$ years old. Round your answer to an integer.

The target heart rate at $$53\%$$ level for someone who is $$22$$ years old is beats per minute.
