Question 931773: How many liters each of a 15% acid solution and a 55% acid solution must be used to produce 80 liters of a 50% acid solution? Round to two decimal places if necessary. Help! Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = liters of 15%
y = liters of 55%
---
x + y = 80
15x + 55y = 50*80
---
put the system of linear equations into standard form
---
x + y = 80
15x + 55y = 4000
---
copy and paste the above standard form linear equations in to this solver:
