Question 959419: A broze alloy is made of copper and tin. A company has 20 pounds of a bronze alloy that is 15% tin. A) write a rational equation to model the amount of pure copper that must be added to the 20 pounds to make an alloy that is 12% tin. Use x to represent the amount of pure copper that is added. B) solve your equation to find how many pounds of pure copper must be added to make an alloy that is 12% tin Answer by lwsshak3(11628) (Show Source):

B) solve your equation to find how many pounds of pure copper must be added to make an alloy that is 12% tin
***
let x=amt of pure copper to add
85%*20+100%x=88%(20+x)
17+x=17.6+.88x
.12x=0.6
x=5
amt of pure copper rmust be added to make an alloy that is 12% tin=5 lbs
