(a) Write a system of equations in which one equation represents the amount of final mixture required and the other represents the percent of acid in the final mixture. Let x and y represent the amounts of the 25% and 50% solutions, respectively.
(b) Use a graphing utility to graph the two equations in part (a) in the same viewing window. (A graphing calculator is recommended.)
~As the amount of the 25% solution increases, how does the amount of the 50% solution change?(c) How much of each solution is required to obtain the specified concentration of the final mixture?

15. [-/6 Points] DETAILS LARCOLALG11 6.2.511.XP. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Forty-five liters of a 40% acid solution is obtained by mixing a 25% solution with a 50% solution. (a) Write a system of equations in which one equation represents the amount of final mixture required and the other represents the percent of acid in the final mixture. Let x and y represent the amounts of the 25% and 50% solutions, respectively. amount of final mixture required percent of acid in the final mixture required (b) Use a graphing utility to graph the two equations in part (a) in the same viewing window. (A graphing calculator is recommended.) O Salation Fes B Need Help? Read it FIL WebAssign Graphing Tool As the amount of the 25% solution increases, how does the amount of the 50% solution change? O As the amount of 25% solution increases, the amount of 50% solution decreases. There is not enough information given. As the amount of 25% solution increases, the amount of 50% solution fluctuates. As the amount of 25% solution increases, the amount of 50% solution increases. As the amount of 25% solution increases, the amount of 50% solution stays the same. L Graph Layers After you add an object to the graph you can use Graph Layers to view and edit its properties (c) How much of each solution is required to obtain the specified concentration of the final mixture? 25% solution 50% solution
