there are 24024 ways that have different winners
(x + 4)*3 - 4 = 65

3x = 65 - 12 + 4
3x = 57 |:3
x = 19 <-- Answer

We know that the ration/percentage that brass is made of remains the same no matter what the weight is;
Therefore, 48 ounces are 80% of the trumpet.
48/80= 0.6 ounce per percent of the zinc (I divided the weight by the percent)
0.6 ounces × 20%= 12 ounces
Therefore, there are 12 ouches of zinc in Henri's trumpet.
Hope I helped :)
