Eagle Electronics..

I have correct answers,

What you need to do is

to show procedure and explain the answers:163, 193,350, 115,-78.50, -78.50

How can I get them

Eagle Electronics must expand by building a second facility. The search has been narrowed down to locating the new facility in one of four cities: Atlanta (A), Baltimore (B), Chicago (C), or Dallas (D) The factors, scores, and weights follow: Site Scores Factor Factor Description Weight 20 1 Labor quality 2 Quality of life 3 Transportation 4 Prozimity to markets 5 Proximity to suppliers 17 Taxes 7 Energy Supplies The composite (weighted average) rating for A= 172 (round your response to two decimal places) The composite (weighted average) rating for B = 202 (round your response to two decimal places) The composite (weighted average) rating for C-377 (round your response to two decimal places) The composite (weighted average) rating for D = 133 (round your response to two decimal places) Based on the given information, using the factor-rating method, the best site for Eagle Electronics' new facility is C

Explanation / Answer

Composite Score for A=20*3+16*2+17*1+16*2+10*1+12*1+9*1=172

Weighted Avg for A=172/100=1.72

Composite Score for B=20*2+16*3+17*1+16*2+10*2+12*3+9*1=202

Weighted Avg for B=202/100=2.02

Composite Score for C=20*4+16*4+17*4+16*3+10*3+12*5+9*3=377

Weighted Avg for C=377/100=3.77

Composite Score for D=20*1+16*1+17*1+16*1+10*1+12*3+9*2=133

Weighted Avg for D=133/100=1.33

Highest score is that of location C.

Part B) When one needs to determine weighted for factor 7 i.e energy supplies.Let W7 be the weight.

Composite rating for Loaction A=20*3+16*2+17*1+16*2+10*1+12*1+1*W7=163+1*W7

Similarly for location B=20*2+16*3+17*1+16*2+10*2+12*3+1*W7=193+1*W7

for Location C=20*4+16*4+17*4+16*3+10*3+12*5+3*W7=350+3*W7

For Location D=20*1+16*1+17*1+16*1+10*1+12*3+2*W7=115+2*W7

Part C) Equations are rightly mentioned in the question Site A<=Site C

i.e. 163+1*W7<=350+3*W7---Eq.1

193+1*W7<=350+3*W7...Eq 2

115+2*W7<=350+3*W7....Eq 3

Solving Eq.1---> 2W7=-187, W7=-93.5

Solving Eq. 2 W7=-78.5

Solving Eq.3 W7=-235

so the final value for W7 stands at -78.5 which satisfies all the three equations
