Question

Jacob reads a number of books in July and 8 books in August. During the same months, Marcus reads 3 times as many books as Jacob,

Jacob lets b represent the number of books he reads in July. He finds that the number of books that Marcus reads during both months is 3 times the sum of
and 8
Write an expression to represent the number of books that Marcus reads during both months.

Answer 1

8 + B x 3 = M

Explanation:

First, you want to add the number of books altogether that Jacob read. This would include 8 plus how much he read in July, but since we don't know what the number is, we use a B for books. Now, you would have 8 + B. This was just the first step, now you have to put in how much Marcus reads. To do this, you will multiply the 8 + B by three because you're trying to find out how much Marcus read in both months. So, this is how I got the answer. I'm not sure how you are supposed to do it, but this is how I did it.
