Final answer:

John has 17 baseball cards.

Step-by-step explanation:

Let x be the number of baseball cards John has.

Cara has 8 times as many baseball cards as John, so Cara has 8x cards.

Together, Cara and John have 153 cards, so we can write the equation:

x + 8x = 153

Combining like terms, we get:

9x = 153

Dividing both sides by 9, we find that:

x = 17

Therefore, John has 17 baseball cards.
