SOLUTION: A chemist needs to make 100 mL of a 30% alcohol solution by mixing 25% and 55% solutions. How much of the 55% solution should the chemist use?
Question 823809: A chemist needs to make 100 mL of a 30% alcohol solution by mixing 25% and 55% solutions. How much of the 55% solution should the chemist use?
You can put this solution on YOUR website! ---
25x + 55y = 30*100
x + y = 100
---
put the system of linear equations into standard form
---
25x + 55y = 3000
x + y = 100
