Question

Emily has 140 books. If Frank were to triple the number of books that he now owns, he would still have fewer than Emily has.

If b = the number of books that Frank has, which mathematical sentence expresses the information above?

Answer 1

B * 3 < 140
B being the number of books Frank owns. Because tripling the amount of books he owns is still less than the amount of book Emily owns, b*3 has to be less than 140

Answer 2

`3b<140`

Explanation:

Let b represent number of books that Frank has.

We have been given that Emily has 140 books.

Triple the number of books Frank would be three times b:
`3b`.

If Frank were to triple the number of books that he now owns, he would still have fewer than Emily has.

This means
`3b` is less than 140. We can represent this information in an inequality as:

`3b<140`

Therefore, the inequality
`3b<140` represents the given scenario.
