Question 1064537: suppose you work in a lab. You need a 200ml of a 35% acid solution for a certain test, but your supplier only ships a 25% solution and a 50% solution. Rather than pay ther hefty surcharge to have the supplier make a 35% solution, you decide to mix 25% acid solution with 50% acid solution, to make your own 35% acid solution. How many milliliters of each solution should you use to form 200ml of a 35% acid solution?

-----
Equation:
acid + acid = acid
0.25x + 0.50(200-x) = 0.35*200
------
25x + 50*200 - 50x = 35*200
--------------------------------------
-25x = -10*200
-----
x = 10*8 = 80 ml (amt. of 25% solution needed)
200-x = 120 ml (amt. of 50% solution needed)
------------
