The <em><u>correct answer</u></em> is:
At least 7 times.
Explanation:
Since 10% of the water in the jug is removed each time, this means that 100-10=90% of the water remains.
After two times, we would have 0.9(0.9) = 0.81 = 81% of the water; each time she pours, the number of times 0.9 is multiplied by itself changes. This makes this an exponential inequality (it is not an equation, as we want "less than half of the water"):
![0.5 < 0.9^x](https://tex.z-dn.net/?f=0.5%20%3C%200.9%5Ex)
To solve this, we will use logarithms:
![\log_{0.9}(0.5)](https://tex.z-dn.net/?f=%5Clog_%7B0.9%7D%280.5%29%3Cx%0A%5C%5C%0A%5C%5C6.58%20%3C%20x%0A%5C%5C%0A%5C%5C7%5Cleq%20x)
The answer is You are a variable
