Question 943281: You need 1275 mL of a 15% alcohol solution. On hand, you have a 10% alcohol mixture and a 95% alcohol mixture. How much of each mixture will you need to obtain the desired solution?
You can put this solution on YOUR website! x = ml of 10% mix
y = ml of 95% mix
---
x + y = 1275
0.10x + 0.95y = 0.15*1275
---
put the system of linear equations into standard form
---
x + y = 1275
0.10x + 0.95y = 191.25
---
copy and paste the above standard form linear equations in to this solver:
