Question

brinlyn increased the amount of water she drank per day from 32 oz to 40 oz. by what percentage did brinlyn increase the amount of water she drank each day?
a 10%
b 20%
c 25%
d 18.75%

Explanation:

Step1: Find the increase in amount

First, we calculate the increase in the amount of water. The original amount is 32 oz and the new amount is 40 oz. So the increase is $40 - 32 = 8$ oz.

Step2: Calculate the percentage increase

The formula for percentage increase is $\frac{\text{Increase}}{\text{Original Amount}} \times 100\%$. Substituting the values, we get $\frac{8}{32} \times 100\%$. Simplifying $\frac{8}{32}$ gives $\frac{1}{4}$, and $\frac{1}{4} \times 100\% = 25\%$.

Answer:

C. 25%
