13*2.50=32.5.

Now he sales baseball cards at 0.75.

So  40.75-32.5=8.25. So I can do this in many ways, but I'll start with the easiest. 8.25/0.75=11. Does this add up? 0.75*11=8.25. Yes, it does!

So your answer is D.

Answer:

11

Step-by-step explanation:

To solve this problem we need to assemble an equation as such:

[tex]2.50b +0.75p = 40.75[/tex]

The b represents the amount of books while the p represents the amount of packaged baseball cards sold.

We are given that Antar sold 13 books that day, in which we have to find how many packages of baseball cards were sold.

By using the formula from before, we can find p:

[tex]2.50b+0.75p = 40.75\\2.50(13) + 0.75p = 40.75\\32.50 + 0.75p = 40.75\\-32.50\\0.75p = 8.25\\(0.75p = 8.25)/.75\\p = 11[/tex]

I am happy to help with any other questions you might have in the future and I will continue to work hard to provide the best answers :)
