Jack need to pick a location to build the warehouse, there are 7 locations to choose from.

let X_i = 1 if location i is chosen, 0 otherwise. i=1,2,3,4,5,6,7, find the right constraint for the statement.

10. Jack need at least 3 warehouses

\f\f\fLocation 2 can be chosen only if location 3 is chosen O a. X2 - X3 SO O b. X2 -X3 20 O C . X2- X3 $ 1 O d. X2 -2X3 + 1so\f
