To determine the best home entertainment center brand for Tammy based on her given weights for different attributes, we need to calculate a weighted score for each brand.
1. Multiply the attribute ratings for each brand by their respective weights.
For Brand A:
Portability: 6 x 0.1 = 0.6
Sound projection: 8 x 0.6 = 4.8
Warranty: 7 x 0.3 = 2.1
For Brand B:
Portability: 9 x 0.1 = 0.9
Sound projection: 6 x 0.6 = 3.6
Warranty: 8 x 0.3 = 2.4
For Brand C:
Portability: 5 x 0.1 = 0.5
Sound projection: 9 x 0.6 = 5.4
Warranty: 6 x 0.3 = 1.8
2. Add up the weighted scores for each brand.
For Brand A: 0.6 + 4.8 + 2.1 = 7.5
For Brand B: 0.9 + 3.6 + 2.4 = 6.9
For Brand C: 0.5 + 5.4 + 1.8 = 7.7
3. Compare the weighted scores of the brands.
Based on the calculations, Brand A has a weighted score of 7.5, Brand B has a weighted score of 6.9, and Brand C has a weighted score of 7.7.
Therefore, the best brand among the three based on Tammy's given weights for the attributes is Brand C with a weighted score of 7.7.
