Hello there! I am EnjoyingLife, and I hope you find my answer helpful.
First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)
Now, let's write an inequality to represent the cost of books.
We know that all books cost less than $5.
We have a sign for "less than". It's "<"
Thus,
p<5
Hope it helps!
Have an awesome day!
Good luck!
