Which of these setups is correct for: "Make V liters of a p% solution by mixing solutions with concentrations of a% and b%, where a < p < b"? Let x be the number of liters of a% solution.

• A. (a/100)(V − x) + (b/100)x = p
• B. ax + b(V − x) = (p/100)V
• C. a/(100x) + b/(100(V − x)) = p/V
• D. (a/100)x + (b/100)(V − x) = (p/100)V
