John and sara each bought the same
of pen and notebook in the school
bookstore, which does not charge sales
tax. john paid $5.55 for two pens and
three notebooks, and sara paid $3.50 for
one pen and two notebooks. how much
does the school bookstore charge for one
notebook?

The school bookstore charges $1.05 for one notebook.

Step-by-step explanation:

Let p = Price of one pen

Let n = Price of one notebook

To begin with, we will construct two simultaneous equations to represent the information given in the problem.

Equation No. 1 -

2p + 3n = $5.55

Equation No. 2 -

p + 2n = $3.50

We will solve these simultaneous equations using either elimination or substitution. For this problem, we will use elimination.

2p + 3n = $5.55 -> (1)

p + 2n = $3.50 -> (2)

We will multiply the second equation by 2 so that both equations have 2p.

2p + 3n = $5.55 -> (1)

2p + 4n = $7.00 -> (2)

We will subtract the values in the second equation from the corresponding values in the first equation.

- n = - $1.05

n = $1.05

Therefore:

The school bookstore charges $1.05 for one notebook.
