Mike bought 4 new baseball trading cards to add to his collections. There are now only twenty nine cards left.

Question

How many cards did Mike start with?

Answer 1

If Mike started with x number of baseball trading cards, and he bought 4 new cards, then the total number of cards he had would be x + 4.

We also know that after buying the new cards, there were only 29 cards left.

So we can set up an equation:

x + 4 = 29

To solve for x, we can subtract 4 from both sides:

x = 25

Therefore, Mike started with 25 baseball trading cards.
