Hugh bought 2 bottles of water. If the total cost of the water was \( \$ 4.50 \), which equation could be used to find the cost of each bottle of water? \( \begin{array}{ll}\text { A. } \$ 4.50 x=2 & \text { C. } \frac{x}{\$ 4.50}=2 \\ \text { B. } \$ 4.50-x=2 & \text { D. } 2 x=\$ 4.50\end{array} \)

To find the cost of each bottle of water, we can set up an equation where \( x \) represents the cost of one bottle of water. Since Hugh bought 2 bottles and the total cost is \$4.50, the equation that correctly represents this situation is \( 2 x = \$ 4.50 \), which corresponds to option D. Simply put, if each bottle costs \( x \), then two bottles would cost \( 2 \times x \). Now imagine you're at a cafe, ready to order a refreshing drink. If you see a sign that states "2 Bottles for $4.50," you would instantly think, "Great, what's the cost per bottle?" Using \( 2x = 4.50 \) means you can easily figure out this price! Just solve for \( x \), and you’ll keep your budget on track while snagging a thirst-quenching deal.
