Archeologists Can Determine the Height of a Human Without Having $h = 65 + 3.14 x$

Archeologists can determine the height of a human without having a complete skeleton. If an archeologist finds only a humerus, then the height of the individual can be determined by using a simple linear relationship. (The humerus is the bone between the shoulder and the elbow.) For a female, if x is the length of the humerus (in centimeters) , then her height h (in centimeters) can be determined using the formula $h = 65 + 3.14 x$ .
For a male, $h = 73.6 + 3.0 x$ should be used.
A female skeleton having a 31-centimeter humerus is found. Find the woman's height at death.

A) $h = 157.04$ centimeters
B) $h = 162.34$ centimeters
C) $h = 107.6$ centimeters
D) $h = 166.6$ centimeters
E) $h = 99.14$ centimeters
