The librarian is selling packages of pens and pencils to students. A package of pens cost $1.50 more than a package of pencils. Write the total cost of a package of pens (y) as a function of the cost of a package of pencils (x). A x = y − 1.50 B x = y + 1.50 C y = x − 1.50 D y = x + 1.50

Option D.

Step-by-step explanation:

Let

y ----> the total cost of a package of pens

x ----> the cost of a package of pencils

we know that

A package of pens cost $1.50 more than a package of pencils

so

The linear equation that represent this problem is

it is x=-4
