PLEASE HELP Based on the information in the instructions, write a system of equations to model the situation. Let n represent the price of a notebook, p represent the price of a package of pencils, and m represent the price of a marker

How much does an individual notebook cost?

How much does a package of pencils cost?

How much does a individual market cost?

Linear Equations
n = notebook

p = a package of pencils

m = marker

an individual notebook cost: $2.75

a package of pencils cost: $1.25

an individual marker cost: $0.5

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
