''Buffalo Shuffle-o'' is a card game in which all the cards are distributed evenly among all players at the start of the game. When Annika and <math>3</math> of her friends play ''Buffalo Shuffle-o'', each player is dealt <math>15</math> cards. Suppose <math>2</math> more friends join the next game. How many cards will be dealt to each player?

We start with <math>4</math> players playing the game (Anika + <math>3</math> friends). When <math>2</math> more players join, there are now <math>6</math> players playing, and since the cards need to be split evenly, this means we can set up the equation <math>\frac{4 \cdot 15}{6} = \frac{60}{6}=\boxed{\text{(C)\ 10}}</math> cards

Problem

$67$ $\textbf{(A)}\ 8 \qquad \textbf{(B)}\ 9 \qquad \textbf{(C)}\ 10 \qquad \textbf{(D)}\ 11 \qquad \textbf{(E)}\ 12$

Solution 1

We start with Annika and $3$ of her friends playing, meaning that there are $4$ players. This must mean that there is a total of $4 \cdot 15 = 60$ cards. If $2$ more players joined, there would be $6$ players, and since the cards need to be split evenly, this would mean that each player gets $\frac{60}{6}=\boxed{\text{(C)\ 10}}$ Buffalo Shuffle-O cards each meaning that the final answer is 10.
