To find the percentage increase, we need to calculate the difference between the new amount and the original amount, and then express that difference as a percentage of the original amount.
The original amount was 32 oz and the new amount is 40 oz.
The difference is 40 - 32 = 8 oz.
To express this as a percentage of the original amount, we divide the difference by the original amount and multiply by 100.
(8/32) * 100 = 25%
Therefore, Brinlyn increased the amount of water she drank each day by 25%.
The answer is C. 25%.
