Question

Liza has 40 fewer than 3 times the number of books

that Janice has. If B is equal to the number of books that
Janice has, which of the following expressions shows
the number of books that Liza and Janice have together?

Answer 1

4B-40

Explanation:

Liza has 40 fewer than 3 times the number of books that Janice has.

This can be represented as: L = 3B - 40, where L is the number of books that Liza has and B is the number of books that Janice has.

Now we need to add their individual numbers of books:

Liza's number of books + Janice's number of books = (3B - 40) + B

So we get:

Liza's number of books + Janice's number of books = 4B - 40

Therefore, the expression that shows the number of books that Liza and Janice have together is 4B - 40.
