The equation to solve is 12p + 11n = 2800 (where p is the cost of a pencil and n is the cost of a notebook and $28 is expressed as 2800 cents).
Make n the subject:
n = (2800-12p)/11.
This is called a diophantine equation as it has lots of solutions.
There are 21 different solutions to this equation:
6c for a pencil and $2.48 for a notebook. Total for one of each is $2.54
17c for a pencil and $2.36 for a notebook. Total for one of each is $2.53
28c for a pencil and $2.24 for a notebook. Total for one of each is $2.52
39c for a pencil and $2.12 for a notebook. Total for one of each is $2.51
50c for a pencil and $2.00 for a notebook. Total for one of each is $2.50
61c for a pencil and $1.88 for a notebook. Total for one of each is $2.49
