Question 1078245: I am having trouble setting up the equations for the following problem:
a goldsmith was going to make some rings out of his 1000 grams of gold an alloy which would contain 45% gold. The goldsmith was going to use 2 different types of alloys and melt them together. One of the alloys was 25% AND THE OTHER 50% GOLD. How many grams of each type would the goldsmith have to use?
I have .25x+.50y=450 so far, but I need one more equation to solve using elimination. please help Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! a goldsmith was going to make some rings out of his 1000 grams of gold an alloy which would contain 45% gold. The goldsmith was going to use 2 different types of alloys and melt them together. One of the alloys was 25% AND THE OTHER 50% GOLD. How many grams of each type would the goldsmith have to use?
x, how much of the 25% gold alloy to use
1000-x, how much of the 50% gold alloy to use
You really need just one variable and one equation. Solve this one here for x, and that will be how many grams of the 25% alloy to use. Computing then 1000-x is simple to do for the 50% alloy.
