The calculation for the number of people at the tournament when 85% of the seats are occupied and the new capacity of the stadium after renovations.
a) Calculation: 85% of 15,000 seats = 0.85 x 15,000 = 12,750 people attended the tournament.
b) Calculation: After renovations, the stadium will hold 100% more people, making the new capacity 15,000 + (100% of 15,000) = 15,000 + 15,000 = 30,000 people.
