A person's systolic blood pressure, which is measured in millimeters of mercury (mm Hg), depends on a person's age, in years. The equation:

$\displaystyle {P}={0.007}{y}^{{2}}-{0.02}{y}+{118}$

gives a person's blood pressure, $\displaystyle {P}$, at age $\displaystyle {y}$ years.

A.) Find the systolic pressure, to the nearest tenth of a millimeter, for a person of age 43 years.



B.) If a person's systolic pressure is 132.52 mm Hg, what is their age (rounded to the nearest single year)?
