Question

Use the formula for determining blood pressure difference from normal, P = |P-120], to solve the problem.

Calculate the pressure difference from normal, P. for a woman whose actual systolic pressure is 103 and whose
normal value should be 120

Answer 1

P = -17

Explanation:

the formula : P = [P - 120]

P is 103 so replace:

P = 103 - 120

subtract them like usually and you should get:

P = -17
