# Problem #1483

 1483 Assume $0 < r < 3$. Below are five equations for $x$. Which equation has the largest solution $x$? $\textbf{(A)}\ 3(1 + r)^x = 7\qquad \textbf{(B)}\ 3(1 + r/10)^x = 7\qquad \textbf{(C)}\ 3(1 + 2r)^x = 7$ $\textbf{(D)}\ 3(1 + \sqrt {r})^x = 7\qquad \textbf{(E)}\ 3(1 + 1/r)^x = 7$ This problem is copyrighted by the American Mathematics Competitions.
