Question 692628: Hi ok so here's my problem: How many ounces of a 15% acid solution and a 40% acid solution must be mixed together to produce 30 ounces of a 33 1/3 acid soltuion?
I know how to do it once I have the equation.
The first equation I had was;
x+y=30
.15x+.40y=30(33 1/3) and then you use combination method but when I tried it I didn't get the right answer?
If you coudl just help me get the equation that would be great thanks so much!
