Ametallurgist has one alloy containing 32% copper and another containing 65% copper. how many pounds of each alloy must he use to make 44 pounds of a third alloy containing 42% copper? (round off the answers to the nearest hundredth.)

Step-by-step explanation:

        First alloy contains 32% copper and the second alloy contains 65% alloy.

We wish to make 44 pounds of a third alloy containing 42% copper.

       Let the weight of first alloy used be in pounds and the weight of second alloy used be in pounds.

       Total weight =        

      Total weight of copper =

       Subtracting 32 times first equation from second equation,

∴ 30.67 pounds of first alloy and 13.33 pounds of second alloy were used.
