SOLUTION: A chemist has a solution of 65% pure acid and another solution of 30% pure acid. How many gallons of each will make 350 gallons of 55% pure acid solution?

Question 939204: A chemist has a solution of 65% pure acid and another solution of 30% pure acid. How many gallons of each will make 350 gallons of 55% pure acid solution?
Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
x = gallons of 65% acid
y = gallons of 30% acid
---
x + y = 350
0.65x + 0.30y = 0.55*350
---
put the system of linear equations into standard form
---
x + y = 350
0.65x + 0.30y = 192.5
---
copy and paste the above standard form linear equations in to this solver:
