An alloy is a mixture of metals suppose that a certain alloy is made by mixing
100 grams of an alloy that contains 28% copper with 28 grams of pure copper how
many grams of copper are in the resulting mixture? What percentage of the
resulting mixture is copper.
       | grams  |  percentage  |  grams of
       |of metal|   of copper  |   copper 
-------|--------|--------------|------------
alloy  |  100   |  28% = 0.28  |100(0.28)=28
-------|--------|--------------|---------
copper |   28   | 100% = 1.00  | 28(1.00)=28
-------|--------|--------------|------------
total  |  128   |              |          56
