answer C

To calculate the rating of Bone Ranch Wave, we need to multiply the scores in each category by their corresponding weights and then sum them up.

Clarity score (4) multiplied by weight (10%): 4 * 0.10 = 0.40
Bouquet score (5) multiplied by weight (5%): 5 * 0.05 = 0.25
Friendliness to the palate score (3) multiplied by weight (5%): 3 * 0.05 = 0.15
Storage ability of opened bottles score (8) multiplied by weight (40%): 8 * 0.40 = 3.20
Price score (9) multiplied by weight (40%): 9 * 0.40 = 3.60

Now, add up the results: 0.40 + 0.25 + 0.15 + 3.20 + 3.60 = 7.60

Therefore, the rating of Bone Ranch Wave is 7.60.

So, the correct answer is C. 7.60.

To calculate the rating for Bone Ranch Wave, you need to use the weighted average formula. Here are the steps:

1. Assign weights to each category: clarity (10%), bouquet (5%), friendliness to the palate (5%), storage ability of opened bottles (40%), and price (40%).

2. Multiply each score by its corresponding weight:
clarity: 4 * 0.10 = 0.40
bouquet: 5 * 0.05 = 0.25
friendliness to the palate: 3 * 0.05 = 0.15
storage ability of opened bottles: 8 * 0.40 = 3.20
price: 9 * 0.40 = 3.60

3. Sum up the weighted scores: 0.40 + 0.25 + 0.15 + 3.20 + 3.60 = 7.60.

Therefore, the rating for Bone Ranch Wave is 7.60.

Looking at the available answer choices, the correct answer is C. 7.60.
