Problem

A tape diagram shows \(\text{juice}:\text{water}~=~3:4\), and a larger mix has \(15~\text{cups}\) of juice. Consider these strategies: A, use the scale factor from \(3\) to \(15\); B, add \(12\) to \(\text{both}~\text{terms}\); C, keep water fixed; D, add the factor to water. Choose the strategy that works, then complete the ratio.
