Answer:

Cara:108

Step-by-step explanation:

John: x number of cards

Cara: 12 times x number of cards(she has 12 times more cards than John)

Cara+John=117 cards

$12 \times x + x = 117 \\ 13x = 117 \\ x = \frac{117}{13} \\ x = 9$

Cara has 12×9 cards, so she has 108 cards.

Hope this was helpful :)
