8. Spring has arrived, and the school has organized a spring outing for the students. However, due to certain reasons, the spring outing is divided into indoor and outdoor activities. The number of people participating in outdoor activities is 480 more than those participating in indoor activities. Now, if 50 people from the indoor activities are transferred to the outdoor activities, the number of people participating in outdoor activities will be exactly 5 times the number of people participating in indoor activities. Therefore, the total number of people participating in indoor and outdoor activities is ( ) people.
【Analysis】Method one: Sum, Difference, and Multiple Analysis

Original

Current

After 50 people from indoor activities were changed to outdoor activities, the number of people outdoors is 580 more than those indoors. Let the number of people indoors be 1 portion, then the number of people outdoors is 5 portions, and 580 people account for 4 portions. The quantity of one portion can be calculated as: $580 \div 4=145$, so the total number of people is: $145 \times(1+5)=870$ (people).
Method two: Equation
Let the original number of people indoors be $\mathrm{x}$, then the number of people outdoors is $(480+\mathrm{x})$. We can set up the equation $530+x=5(x-50)$, solving for $x=195$, so the total number of people is $(480+195)+195=870$ (people).
