Final answer:
To determine the total number of visitors in the park, we set up a proportion with the given percentage, 35%, and the number of visitors who stayed at the campground, 105. Solving this proportion reveals that the park had 300 visitors that day.
Step-by-step explanation:
The question relates to the concept of percentages in mathematics. We are given that 35% of the park's visitors stay at the campground, and it is known that 105 visitors stayed at the campground. To find the total number of visitors, we can set up a proportion where 35% corresponds to the 105 visitors that stayed at the campground.
Step 1: Convert the percentage to a decimal by dividing by 100. So, 35% becomes 0.35.
Step 2: Use the proportion to find the total number of visitors. Let the total number of visitors be X. Then, we can write the equation:
0.35 (X) = 105
Step 3: Solve for X by dividing both sides of the equation by 0.35:
X = 105 / 0.35
X = 300
Therefore, the park had 300 visitors that day.
