Answer 2

Calculation of the Total Number of Participants in the Sports Competition

To calculate the total number of participants in the sports competition, we need to analyze the information provided.

According to the given information: - On the first day, 34% of all athletes participated. - On the second day, 30% of all athletes participated. - On the third day, the remaining 108 athletes participated.

Let's assume the total number of participants in the competition is "x."

Based on the given information, we can create the following equation:

0.34x + 0.30x + 108 = x

Simplifying the equation:

0.34x + 0.30x - x = -108

0.64x - x = -108

-0.36x = -108

Dividing both sides of the equation by -0.36:

x = -108 / -0.36

x = 300

Therefore, the total number of participants in the sports competition was 300.

Please note that the given equation assumes that each athlete participated on only one day.
