Question

At​ noon, a tank contains 5 in of water. After several​ hours, it contained 3 in of water. What is the percent decrease of water in the​ tank?

Answer 1

Answer: To calculate the percent decrease of water in the tank, we can use the following formula:

Percent decrease = (Initial value - Final value) / Initial value x 100%

In this case, the initial value of water in the tank is 5 inches and the final value is 3 inches. So, the percent decrease is:

(5 - 3) / 5 x 100% = 2 / 5 x 100% = 40%

So, the percent decrease of water in the tank is 40%.
