3 10 + 5 = 15 5
4 15 + 5 = 20 0

<h3>How to represent the required expression</h3>
Information gotten from the data include
Emily has 300 books
Frank were to double the number of books that he now owns, he would still have fewer than Emily has.
Let the number of books owned by frank be b and from the information we have that:
2b < 300
b < 150
hence the number of books owned by frank, b less than 150
