question 15

Multiple Choice

Solve the problem.
-A pharmacist wants to mix a $16 \%$ saline solution with a $26 \%$ saline solution to get $15 \mathrm {~L}$ of a $20 \%$ saline solution. How much of each solution should she use?

• A) \(10 \mathrm {~L}\) of the \(16 \%\) solution; \(5 \mathrm {~L}\) of the \(26 \%\) solution
• B) \(5 \mathrm {~L}\) of the \(16 \%\) solution; \(10 \mathrm {~L}\) of the \(26 \%\) solution
• C) \(9 \mathrm {~L}\) of the \(16 \%\) solution; \(6 \mathrm {~L}\) of the \(26 \%\) solution
