Suppose you are building a linear optimization model to help decide where to build new cell towersfor your mobile phone company. There are three possible locations for your cell towers which arereferred to as site A, site B, and site C. The decision variables are xA, XB and XC.Let xA1 if you choose to build a cell tower on site A, and O if you choose NOT to build a cell toweron site A. Let xB1 if you choose to build a cell tower on site B, and 0 if you choose NOT to build acell tower on site B. Let xC - 1 if you choose to build a cell tower on site C, and 0 if you chooseNOT to build a cell tower on site C.Because of the geography of the locations and your desire to provide adequate cell coverage forcustomers, you know that if you choose to build a cell tower on site C, you must also build a sitetower on site A or on site B (or both). Which of the following constraints will achieve this logicalrequirement?OxC <- xA+xBO Requires 2 constraints: xC <= xA AND XC <=xBO XC XA XBOXA <=xB <- xC

Given that if you build a cell tower in C then you must build one on site A or on B or both.

Because of the geography of the locations and your desire to provide adequate cell coverage for customers, you know that if you choose to build a cell tower on site C, you must also build a site tower on site A or on site B (or both). Which of the following constraints will achieve this logical requirement? OxC<=xA+xB O Requires 2 constraints: xC <=xA AND XC <=xB XEC XÃ XB OXA <=xB < xC
