Final answer:
To find out how many calories would be contained in a 12 fluid ounce bottle of vitamin water, we use a proportion to solve for x. The 12 fluid ounce bottle would contain 187.5 calories.
Step-by-step explanation:
To find out how many calories would be contained in a 12 fluid ounce bottle of vitamin water, we can set up a proportion. Since 8 fluid ounces contain 125 calories, we can write the proportion as:
8 fluid ounces / 125 calories = 12 fluid ounces / x calories
We can cross-multiply and solve for x:
8 * x = 125 * 12
x = (125 * 12) / 8 = 187.5 calories
Therefore, a 12 fluid ounce bottle of vitamin water would contain 187.5 calories.
