Percentage Help!!!
Fanning and Medal

anonymous · Answer

Use a clock or stopwatch to take your pulse rate while sitting relaxed. Record the number of beats for 30 seconds. Now, walk out your front door and run around your house, then come back inside. Take your pulse again and record the number of beats for 30 seconds.

What is the percent increase in your pulse rate? Show your work. Round your percent to the nearest whole number. 
Sitting Down: 37
Running: 64

thxs for looking

anonymous · Answer

Well, remember that percentage increase is given by:

$$\frac{ (P_f - P_i) }{ P_i }*100$$

So, that's the numerical increase over original amount * 100 for percentage.

P_f is final pulse, P_i = initial pulse.
