PLEASE HELP

A company has established a distribution system for the supply of critical components. Currently there are two origins for these components, which must be shipped to three plants. The current network has the following characteristics:

COSTS	Plant 1	Plant 2	Plant 3	Supply
source 1	$7	$11	$10	400
source 2	$3	$6	$5	600
Demand	600	450	550

The firm has identified two potential sites for a third component source; these are identified as Source A and Source B. From A, the costs to ship would be $13 to Plant 1, $8 to Plant 2, and $12 to Plant 3. From B, these costs would be $9, $8, and $7. The new source, wherever it is located, will have a capacity of 550 units. Solve with the transportation method. Which site should be selected?

a. Is the problem balanced? [ Select ] ["no", "yes"] If not, which area is short? [ Select ] ["supply; 50 units", "supply; 100 units", "demand; 150 units", "neither, the problem is balanced", "demand; 75 units"]

a. What is the cost when evaluating Source A? [ Select ] ["$9,450", "$4,500", "$10,200", "$9,600", "$9,300"]

b. What is the cost when evaluating Source B? [ Select ] ["$9,650", "$8,850", "$1,200", "$10,100", "$8,760"]

c. Which site should be selected?
