(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.

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.
