A football game was played between two teams, the Cougars and the Panthers. The two teams scored a total of $34$ points, and the Cougars won by a margin of $14$ points. How many points did the Panthers score?

$10$

$14$

$17$

$20$

$24$

Solution:

Let $c$ and $p$ be the Cougars' and Panthers' scores. Then $c + p = 34$ and $c - p = 14.$

Subtracting gives $2p = 20,$ so $p = 10.$

Thus, the correct answer is A.
