25% 6 divided by 24 will give you the percentage of copper in the bar
Given:
Vertex ===> (h, k) (2, 4)
The parabola passes through the point: (x, y) ==> (3, 6)
Let's find the equation of a parabola.
To find the equation, use the general equation of a parabola with vertex (h, k):

Where:
(h, k) ==> (2, 4)
(x, y) ==> (3, 6)
Substitute values into the general equation:

Subtract 4 from both sides:

Substitute 2 for a, and input the values of the vertex (h, k) in the general vertex equation:

Therefore, the equation of the parabola is:

Answer:
3·(x - 14) + 1 = - 4·x + 5
3·x - 42 + 1 = - 4·x + 5
3·x - 41 = - 4·x + 5
7·x - 41 = 5
7·x = 46
x = 46/7
