Can Someone explain how to do step B -step by step. I posted answers but I am not sure how to do B.

Bindley Corporation has a one-year contract to supply motors for all washing machines produced by Rinso Ltd. Rinso manufactures the washers at four locations around the country: New York City, Fort Worth, San Diego, and Minneapolis. Plans call for the following numbers of washing machines to be produced at each location:

New York City	55,000
Fort Worth	71,000
San Diego	75,000
Minneapolis	75,000

Bindley has three plants that can produce the motors. The plants and production capacities are

Boulder	110,000
Macon	80,000
Gary	165,000

Due to varying production and transportation costs, the profit Bindley earns on each 1,000 units depends on where they were produced and where they were shipped. The following table gives the accounting department estimates of the dollar profit per unit. (Shipment will be made in lots of 1,000.)

	SHIPPED TO
PRODUCED AT	NEW YORK CITY	FORT WORTH	SAN DIEGO	MINNEAPOLIS
Boulder	7	15	11	14
Macon	26	18	10	11
Gary	10	22	17	15

Given profit maximization as a criterion, Bindley would like to determine how many motors should be produced at each plant and how many motors should be shipped from each plant to each destination.

A) Develop a transportation grid for this problem.

From/To	New York City	Fort Worth	San Diego	Minneapolis	Supply
Boulder	7	15	11	14	110,000
Macon	26	18	10	11	80,000
Gary	10	22	17	15	165,000
Requirements	55,000	71,000	75,000	75,000

B)Find the optimal solution using Microsoft Excel.Note: Leave no cells blank - be certain to enter "0" wherever required.

Candidate Solution	New York City	Fort Worth	San Diego	Minneapolis	Total Shipped
Boulder	0	0	0	56,000	56,000
Macon	55,000	0	0	0	55,000
Gary	0	71,000	75,000	19,000	165,000
Total supplied	55,000	71,000	75,000	75,000	276,000

Boulder	0	0	0	784,000
Macon	1,430,000	0	0	0
Gary	0	1,562,000	1,275,000	285,000
