I need the answer. ASAP

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
Philly	$7	$11	$10	400
Allentown	$3	$6	$5	600
Demand	600	450	550

The firm has identified two potential sites for a third component source; these are identified as Harrisburg and Pittsburg.

From Harrisburg, the costs to ship would be $13 to Plant 1, $8 to Plant 2, and $12 to Plant 3.

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

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

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

c. Which site should be selected? [ Select ] ["cannot determine based on the information given", "Pittsburg", "Neither", "Harrisburg"]
