First we need to write the equations for the given scenario. Using the equations, we can form a system of matrix for the situation.
Let the customer buys, x pounds of almonds, y pounds of cashews and z pounds of walnuts. Since he buys 12 pounds of mixed nuts, we can write:
Total cost of these mixed nuts was $118. So we can write:
Customer buys 2 more pounds of walnut than cashews. So, we can write:
Using these equations, we can set up the system of matrix as shown below in the image.

Using simple interest, it is found that her interest charge this month will be of $30.
<h3>Simple Interest</h3>Simple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
I(t) = Prt
In which:
- P is the initial amount.
- r is the interest rate, as a decimal.
In this problem, considering the time in years, the parameters are:
Hence:
Her interest charge this month will be of $30.
