Multiple Choice

How many milliliters of a 5% acid solution and a 13% acid solution should be used to make 200 ml of an 8% acid solution? Choose the system that would solve the application. Let x = number of liters of 5% acid solution and y = number of liters of 13% acid solution.

• A) \(\left\{ \begin{array} { l }
• x + y = 200 \\
• .05 x + .13 y = 16
• \end{array} \right.\)
• B) \(\left\{ \begin{array} { l }
• x + y = 200 \\
• .05 x + .13 y = 200
• \end{array} \right.\)
• C) \(\left\{ \begin{array} { l }
• x + 200 = y \\
• .05 x + .13 y = 16
• \end{array} \right.\)
• D) \(\left\{ \begin{array} { l }
• x + y = 200 \\
