The approximate age of a woman whose normal systolic pressure measures 125 mm Hg is 31
The function is given as:

When the normal systolic pressure is 125, it means that:

So, we have:

Subtract 125 from both sides of the equation

Using a graphing calculator, we have:

But age cannot be negative.
So, we have:

Approximate

Hence, the age of the woman is 31
