please solve properly..

1) There are three security companies serving to three cities. Cities 1 and 2 requires 2 security personnels while city 3 requires 3 security personnels. The cost of responding to each incident depends on the time at which security personnels arrive. For instance if tij is the time when ith personnel arrives to city j, then the cost of responding to that incident is given in below equations. Incident at city 1:4t11+6t12 Incident at city 2:7t21+3t22 Incdent at City 3:6t31+4t32+8+33 If three security companies can respond to all cities, and company 1 has 3 security personnels and companies 2 and 3 each have 2 security personnels, and the time it takes to arrive from each company to each city is given in Table 1 then formulate a balanced transportation table, minimizing the cost of incidents at each city. (There must be 7 demand points!!!) (30 pts)
