What is the key information in this problem?

• Jenna and Luke played a game.

• They each scored 80 points. Luke got 8 more and Jenna got n fewer.

• Jenna scored more than Luke and they. had a total of 80 points.

• Luke scored 8 more than n.

• 80 + n - 8

• 80 + 8 - n

• 80 - 8 - 8

• 80 - n - 8

If Jenna received 2 fewer points than Luke in the bonus round, how many total points did she earn?

• 80 + 8 - 2 = 86

• 80 + 2 - 8 = 74

• 80 - 8 - 8 = 64

• 80 - 2 - 8 = 70
