Answer 2

Hi! :)

This problem is fairly simple when you think about it.

We know that Luis already has 25 cards, and he gets 5 new ones everyday for 20 days. This means all you have to do is multiply 5 by 20 and then add it to 25. 

So:

5*20=100

25+100=125

At the end of day 20 Luis should have 125 baseball cards. 

Hope this helps!
