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: P = 0.007y – 0.01y + 118 gives a person's blood pressure, P, at age y years. A.) Find the systolic pressure, to the nearest tenth of a millimeter, for a person of age 48 years. P=133*6 B.) If a person's systolic pressure is 135 mm Hg, what is their age (rounded to the nearest whole year)?

Question
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:
P =
0.007y? – 0.01y + 118
gives a person's blood pressure, P, at age y years.
A.) Find the systolic pressure, to the nearest tenth
of a millimeter, for a person of age 48 years.
P=133*6
B.) If a person's systolic pressure is 135 mm Hg,
what is their age (rounded to the nearest whole
year)?
49
