5 points

55 points

25 points

30 points

Gianna earned 25 + 30 = <<25+30=55>>55 points after the first two rounds. Answer: \boxed{55}.

To find the total points earned, we need to add the points earned in the first and second rounds.

In the first round, Gianna earned 25 points.

In the second round, she earned 30 more points.

So, the total points earned after the first two rounds is 25 + 30 = 55 points.

Therefore, the correct answer is 55 points.

To determine the total points Gianna has earned after the first two rounds, you need to add the points she earned in the first round to the points she earned in the second round.

In the first round, Gianna earned 25 points.

In the second round, she earned an additional 30 points.

To find the total points, add 25 (points from the first round) to 30 (points from the second round).

25 + 30 = 55

Therefore, Gianna has earned a total of 55 points after the first two rounds.
