Question

beats per minute

Answer 1

Step-by-step explanation:

To find the answer, you set up an equation: You put the 20% into decimal form by sliding the decimal place two spaces to the left. The "x" represents the grizzly bear's normal heart rate. A grizzly bear's normal heart rate when it is not hibernating is 50 beats per minute.
