3.

A football game was played between two teams, the Cougars and the Panthers. The two teams scored a total of 3434 points, and the Cougars won by a margin of 1414 points. How many points did the Panthers score?

1010

1414

1717

2020

2424

Solution:

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

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

Thus, the correct answer is A.
