Using a system of equations, it is found that:
- Each individual notebook costs $2.75.
- A package of pencils costs $1.25.
- Each individual marker costs $0.5.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- n is the price of a notebook.
- p is the price of a package of pencils.
- m is the price of marker.
From Stan's purchases, we have that:
From Jan's purchases, we have that:
From Fran's purchases, we have that:
From the third equation:
Replacing on the first:
On the second equation, we have that:
Finally:
Then:
- Each individual notebook costs $2.75.
- A package of pencils costs $1.25.
- Each individual marker costs $0.5.
