Calculate the x-coordinate of the center-of-gravity

Question

Sylva Warehousing desired to locate a central warehouse to serve five North Carolina markets. Placed on a grid system, its five markets had coordinates and demand as follows: The (X,Y) coordinates, in miles, for the five markets are: M1 = (45,65); M2 = (120,55); M3 = (200,105); M4 = (100,200) and M5 = (195,175). The projected annual demand for each of the markets is: V₁ = 2,200 units, V₂ = 900 units, V₃ = 1,300 units_, V₄ = 1,750 units and V₅ = 3,100 units.

1. Calculate the X-coordinate of the center-of-gravity location using the center-of-gravity technique. (Round value to nearest integer)
2. Calculate the Y-coordinate of the center-of-gravity location using the center-of-gravity technique. (Round value to nearest integer)
