An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 110 grams of an alloy containing 16% copper with 210 grams of an alloy containing 64% copper. How many grams of copper are in the resulting mixture? and what percentage of the resulting mixture is copper?
+129840 Well, if we have a 110 gram alloy that contains 16% copper, then there must be .16 * 110 = 17.6 g of copper in the alloy
And if we have a 210 gram alloy that contains 64% copper, then there must be .64 * 210 = 134.4 g of copper in this alloy
So , the final mixture contains (17.6 + 134.4)g of copper = 152g of copper
And the total final mixture of both alloys = (110 + 210) g = 330g
And if 152g of this is copper...... then, 152 / 330 = about 46% is copper
