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.

Answer:
9
Step-by-step explanation:
3/4×12 =12 ×3 :4 =36 :4 =9 ice pops
X = or > -21/2 with the problem.
Answer:
x = 2 4/7
Step-by-step explanation:
8x - 9 = x + 9
Add 9 to both sides
8x - 9 + 9 = x + 9 + 9
8x = x + 18
Collect like terms
8x - x = 18
7x = 18
Divide both sides by 7
7x/7 = 18/7
x = 2 4/7
Answer:
3/24= 33/264
2/9= 12/54
4/5= 32/40
8/9= 16/18
42/18= 7/3
32/12= 8/3
