I don't know how to set this one up. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! : Kimberly and Andrew use a metal alloy that is 27.32% copper to make jewelry.
how many ounces of a 26% alloy must be mixed with a 29% alloy to form 75 ounces of the desired alloy?
:
Set it up this way.
:
Let x = amt 29% alloy required
The total is to be 75 oz, therefore
(75-x) = amt of 26% alloy required
:
.29x + .26(75-x) = .2732(75)
