You can put this solution on YOUR website! A metal alley is a metal made by blending two or more types of metal. A jeweler has supplies of two metal alloys. One metal alloy is 30% gold and the other is 10% gold. How much of each alloy should the jeweler combine to create 4 kilograms of an alloy containing 15% gold?
let x=amt 0f 30% alloy to use
4-x=amt 0f 10% alloy to use
30%x+10%(4-x)=15%*4
.30x+.40-.10x=0.60
.20x=0.20
x=1
4-x=3
amt 0f 30% alloy to use=1 kg
amt 0f 10% alloy to use=3 kg
