Question 616933: I have 2 mixture questions I am currently stuck on that are actually of the free tutor, "rrapalje" own webpage.
question 1: How much water must be added to a 50% alcohol solution to obtain 100L of a 10% solution?
question 2: 50 tickets where sold for a BBQ at a total of $219. Prices where $2.50 children, $3.50 youth, $5.00 adults. There were 10 more youth tickets than childrens tickets. How many of each tickets were sold?
If you could give me step by step of how to make the equations from the words I would be very great full. Many thanks, Jim.

You can put this solution on YOUR website! Why not ask "rrapalje"?
It is his problem.
Submit one problem at a time and no similar problems.
I will do the second.
a+y+c=50;
y=c+10;
2.5c+3.5y+5a=219
Now you have three equations with three unknowns. Solve with your favorite method.
Enjoy
a=32, c=4, y=14
