Wilson purchased a notebook for class for $5. he also purchased x pens for 1.50 each. write the linear function to model wilson's purchase.

Step-by-step explanation:

Let the total purchase be given as 'p' dollars.

Given:

Price of a notebook = $5

Price of a pen = $1.50

Number of pens purchased = 'x'
