we are given with an initial value of water equal to 12 ounces of water and the final value of water is 2 1/4 or 2.25 ounces. Since the two substances are the same, we can use direct subtraction to determine what was consumed after walking. The answer is 12-2.25 equal to 9.75 ounces

Answer: \(9\dfrac{3}{4}\text{ ounces}\)

Step-by-step explanation:

Given : The initial amount of the water when Carrie started her walk = 12 ounces

The amount of water after she finished her walk = \(2\dfrac{1}{4}\text{ ounces}=\dfrac{9}{4}}\text{ ounces}\)

Then , the water she had drunk is given by :-

\(12-\dfrac{9}{4}=\dfrac{48-9}{4}\\\\=\dfrac{39}{4}=9\dfrac{3}{4}\)

Hence, the amount of water she had drunk =  \(=9\dfrac{3}{4}\text{ ounces}\)
