Consider the following data for a Transportation Problem with 4 origins (in column 1) and 6 destinations (in row 1).

$/unit	Atlanta	Boston	Denver	Miami	Montreal	Seattle	Supply
Chicago	2	4	5	5	3	5	600
Dallas	1	3	3	6	1	4	400
San Diego	1	5	7	3	7	2	600
Toronto	4	2	3	5	2	6	600
Demand	150	200	200	400	300	300

1. Suppose that the Canadian destination (Montreal) must be served from the Canadian origin (Toronto). (This means, Montreal must be served by Toronto, but Toronto can serve other places, too.) How much does this restriction increase the cost?

a. Minimum cost = ________________________

b. % increase over cost from #1a. = ______________

c. Fill in the table below with the optimal product flows in the empty box, the flow out of each origin in the rowsum column, and the flow into each destination in the colsum row.
