Question 936045: A merchant wishes to blend 200 pounds of coffee worth $3.20 a pound from two mixtures: one at $3.00 a pound and the other at $3.25 a pound. How many pounds of each mixture should he use? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = pounds of $3.00 mixture
y = pounds of $3.25 mixture
---
x + y = 200
300x + 325y = 320*200
---
put the system of linear equations into standard form
---
x + y = 200
300x + 325y = 64000
---
copy and paste the above standard form linear equations in to this solver:
