Bivin is the fitness director at Lake Air Fitness Center. He recommends that the intensity of aerobic activities be measured by pulse rate. Following generally accepted practice, he recommends that the clients achieve a pulse rate depending on their age and level of activity. The target pulse rate is determined as follows: Subtract the person's age from 220 to obtain a "maximum pulse rate." Those beginning aerobic activities should exercise at a level so that their pulse rate (per minute) is 40% of their maximum rate. For burning calories, the person should exercise at a level that achieves 60% of his or her maximum rate. Write the equations that give the relationship between a person's age and desired pulse rate for the following. (Use x for person's age and p for pulse rate.)
(a) the beginner

(b) the person desiring to burn calories
