Final answer:
Celia's resting heart rate r can be found by setting up the equation 124 = r + 62 and solving for r. After subtracting 62 from both sides, we find that Celia's resting heart rate is 62 beats per minute.
Step-by-step explanation:
To find Celia's resting heart rate r, we can set up an equation using the information provided. We know that Celia's current heart rate is 124 beats per minute, and this is 62 beats more than her resting rate. We can express this relationship algebraically:
124 = r + 62
To solve for r, we need to isolate the variable. We subtract 62 from each side of the equation to find the resting heart rate:
124 - 62 = r
r = 62 beats per minute
This means Celia's resting heart rate is 62 beats per minute.
