Final answer:
To find the average attendance at Madrid football club in 1998 given a 7% decrease in 1999 equivalent to 2030 fewer attendees, we set up an equation 0.07 * x = 2030 and solved for x, yielding an attendance of 29,000 in 1998.
Step-by-step explanation:
The student asked how many people attended Madrid football club matches in 1998 if there were 2030 fewer attendees in 1999, which was a 7% decrease. To solve this, we need to understand that the 7% decrease represents the 2030 people who did not attend in 1999. Therefore, we calculate the total attendance in 1998 by considering 2030 as 7% of the total 1998 attendance.
Let x be the total attendance in 1998. The equation is:
0.07 * x = 2030
Dividing both sides by 0.07 gives us:
x = 2030 / 0.07
x = 29000
Therefore, the average attendance at Madrid football club in 1998 was 29,000 people.
