Mandy and Jordan each bought some of the same notebooks and the same three-ring binder. Mandy paid $5.85 for 3 notebooks and 1 binder. Jordan paid $4.65 for 2 notebooks and 1 binder.

What is the price of one of the notebooks?

1 notebook costs $3.45
let's turn this into 2 equations, n being notebook price, and b being binder price ->
mandy -> 3n + b = 5.85 jordan -> 2n + b = 4.65
we need to take one equation, simplify for b, and plug it into the other equation, let's take jordan's equation for this ->
b = 4.65 - 2n
plug it into mandy's equation
3n + (4.65 - 2n) = 5.85
simpify until you get n = 1.20 take this and plug it back into jordan's equation ->
2(1.20) + b = 4.65 simplify until you get b = 2.25 plus this value into mnady's equation ->
3n + (2.25) = 5.85 simplify until you get that n = 2.25

The price of one notebook is $1.20. This is found by solving a system of equations based on the amounts that Mandy and Jordan paid for their notebooks and binders. Mandy's and Jordan's total prices were set up into two equations, which were then solved to find the cost of one notebook.
