Brin increased the amount of water she drank per day from 32 oz to 42 oz. By what percentage did Brin increase the amount of water she drank each day?
A. 8%
B. 18.75%
C. 20%
D. 25%
To find the percentage increase, we can use the formula:
\(\text{percentage increase} = \left(\frac{\text{increase in quantity}}{\text{original quantity}}\right) \times 100\)
The increase in quantity is \(42 - 32 = 10\) oz, and the original quantity is 32 oz. Plugging these values into the formula, we get:
\(\text{percentage increase} = \left(\frac{10}{32}\right) \times 100 \approx 31.25\%\)
Therefore, Brin increased the amount of water she drank by approximately 31.25%.
None of the given answer choices are correct.
However, if we round this to the nearest whole number, the closest answer choice is D, 25%.
