Question

6. Calculate Suppose Cory's
blood pressure is 125 at its
highest point. To return his
blood pressure to normal,
Cory must reduce it by what
percentage? (Show your
work.)

Answer 1

Answer:

Let's suppose that the ideal blood pressure is 100 (the ideal values are between 90 and 110, i am taking the middle value)

If 125 is the 100%, and we want to go to 100, then we need to decrease by:

125 - 100 = 25

now, to calculate the percentage that represents the 25, we need to calculate:

(25/125)*100% = 20%

So to reduce his blood pressure to normal, he must reduce it by 20%
