Could I have help with my math worksheet?

Exercise 3. On Wednesday, you need to create 2L of a 50% alcohol solution using dierent amounts of the 40% and 80% solutions. You decide you are tired of solving these equations everyday, so you spend some time creating a formula that will tell you how much of the 40% and 80% solutions to use to get 2L of a solution with your desired concentration. (a) Let as be the amount of 80% solution used, and let 3; be the amount of 40% solution used to make 2L of a solution that is 100 * 30%. (Here p is the decimal form of the solution concentration. If you have an 87% alcohol solution, then 13 = 0.87.) Write a system of equations that you can solve to nd 53 and y. (b) Solve the equation in part (a), assuming p is constant. (c) Use your formula to determine the amount of 40% and 80% solutions needed to create 2L of 50% solution. ((1) Describe the values of p for which your formula in part (b) will work
