You can put this solution on YOUR website! Twenty ounces of a 40% gold alloy are mixed with 80 oz of a 20% gold alloy. Find the percent concentration of the resulting gold alloy.
:
let x = the resulting per cent of mixing the two alloys
40(20) + 20(80) = x(20+80)
800 + 1600 = 100x
2400 = 100x
x = 2400/100
x = 24% is the resulting per cent
