Your friend, Jordon, is a chemist trying to create a new solution from three different solutions. She has three beakers that contain a specific acid solution. There are 8 ounces of a 10% acid solution in the first beaker, 10 ounces of a 20% acid solution in the second beaker, and the third beaker has a 45% acid solution. She wants to mix the three beakers to create a 35% acid solution. How many ounces she should take from the third beaker if she is going to use the entire solution from the first two beakers?
