You can put this solution on YOUR website! An alloy of tin and copper has 6 pounds of copper for every 2 pounds of tin.
If 200 pounds of this alloy are made, how many pounds of tin are used?
---
6:2 is the same as 6x:2x where 2x is the amount of tin
-----
Equations:
2x + 6x = 200
8x = 200
x = 25
----
Amount of tin = 2x = 2*25 = 50 lbs.
