One disadvantage of investing in precious metals is that other metals change their values more easily (option C).
<h3>How does the value of metals behave?</h3>
Precious metals such as gold and silver are metals that hardly change their price because they serve as a standard to set the price of other metals.
However, its value is not always the most suitable for making investments. Although they do not lose value over time. Many people prefer to make investments in other metals such as steel or iron because these change their price according to supply and demand.

The maximized value of the objective function is 38
The objective function is given as:
Max P = 5x + 3y
The constraints are given as:
- 3x + 6y ≤ 48
- 2x + 8y ≤ 56
- x ≥ 0 y ≥ 0
To do this, we make use of the graphical method.
See attachment for the graph of the constraints.
From the graph, we have the following feasible point

Substitute 4 for x and 6 for y in the objective function.

So, we have:



Hence, the maximized value of the objective function is 38
