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.

Answer:
11.6
Step-by-step explanation:
Hopefully you want it solved, because that's what I'm about to do!
In order to solve this, you need to insert the value of t (which is 4.2) into the equation.
w(t) = 3 (4.2) - 1
Now that 4.2 is in the place of t, you solve it like you would any equation. Starting with multiplying 3 and 4.2 to get 12.6, and then subtracting one from that to get 11.6
Hope this helps!
