The correct answer is 25%.
Amanda can paint the room by herself in 8 hours. Therefore, she can paint \(\frac{1}{8}\) of the room in an hour. In the same way, Dani can paint \(\frac{1}{x}\) of the room in an hour. Together, they can paint \(\frac{1}{6}\) part of the room in an hour. Now, write the equation and solve for x.
\(\frac{1}{8}+\frac{1}{x}=\frac{1}{6}⇒\frac{1}{6}-\frac{1}{8}=\frac{1}{24}⇒x=24\)
Dani can paint the room in 24 hours. Then, in six hours, Dani paints \(\frac{6}{24}\) or \(\frac{1}{4}\) part or 25% of the room.
