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 total shipped from each origin must be either zero or at least 200. (For example, Chicago must send either nothing to any destination - or a total of 200 or more to some combination of destinations.) How much does this restriction increase the cost from the original cost in #1a?

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.
