Liliane has $50\%$ more soda than Jacqueline, and Alice has $25\%$ more soda than Jacqueline. What is the relationship between the amounts of soda that Liliane and Alica have?


$\textbf{(A) }$Liliane has $20\%$ more soda than Alice. $\textbf{(B) }$Liliane has $25\%$ more soda than Alice. $\textbf{(C) }$Liliane has $45\%$ more soda than Alice. $\textbf{(D) }$Liliane has $75\%$ more soda than Alice. $\textbf{(E) }$Liliane has $100\%$ more soda than Alice.

Solution

Let's assume that Jacqueline has $1$ gallon of soda. Then Alice has $1.25$ gallons and Liliane has $1.5$ gallons. Doing division, we find out that $\frac{1.5}{1.25}=1.2$, which means that Liliane has 20% more soda. Therefore, the answer is $\boxed{\textbf{(A)}\text{Liliane has$ (Error compiling LaTeX. Unknown error_msg)20\%$more soda than Alice.}}$ (Error compiling LaTeX. Unknown error_msg)
