The formula to compute a person's body mass index is B = 700 x W/H2 (W/H2 means W/h squared, the h is squared)

Part A: Solve B = 700 x W/h2 for the variable W.

Part B: What is the weight to the nearest pound of a person who is 64 inches tall and has a body mass index of 21.45?

By "solve" in part A, do you mean make W the subject of the formula? In which case:

A: B = 700 x W/h2

B x h2 = 700 x W

(B x h2) / 700=W

B: (21.45 x 64^{2}) / 700=W

87859.2/700=W

126=W

126 pounds
