Final answer:

Lamar drinks a total of 546 ounces of water per week. This is calculated by summing his daily water intake (78 ounces) and multiplying it by 7 days. His intake surpasses general recommendations for daily water intake, emphasizing the need for personalized hydration plans.

Explanation:

To calculate the total amount of water Lamar drinks in a week, we first need to add together the amounts he drinks in a day. Lamar drinks 8 ounces with breakfast, 6 ounces with his vitamins, 16 ounces with lunch, 16 ounces with dinner, and 32 ounces throughout the day. The total daily water intake is 8 + 6 + 16 + 16 + 32 = 78 ounces per day.

Next, we will multiply Lamar's daily intake by 7 to find out his weekly intake: 78 ounces/day × 7 days/week = 546 ounces/week.

The result indicates that Lamar drinks a total of 546 ounces of water in a week. This is above the general recommendations for daily water intake, which highlight the importance of individualized daily water consumption based on factors like body weight and activity levels.
