Question 56817: When you exercise your pulse rate rises. Recommended pulse rates vary with age and physical condition. For vigorous exercises, such as jogging, the compound inequality 0.7(220-a)<=R<=0.85(220-a) gives a target rate for pulse rate R (in beats per minute), based on age A in years).
What is the target range for pulse rates for a person 35 years old? Round your answer to the nearest beat per minute.
Imagine that your cousin's target pulse rate is in the range between 140 and 170 beats per minute. What is your cousin's age?
