Calculation of the Number of City Residents Who Watched the Champions League Final on TV

To calculate the number of city residents who watched the Champions League final on TV, we need to follow these steps:

1. Determine the total population of the city. 2. Calculate the number of residents who are not interested in football. 3. Calculate the number of football fans. 4. Calculate the number of football fans who watched the Champions League final on TV.

Let's go through each step in detail.

Step 1: Determine the Total Population of the City

The total population of the city is given as 80,000 residents.

Step 2: Calculate the Number of Residents Who Are Not Interested in Football

According to the information provided, 40% of the city's residents are not interested in football. To calculate the number of residents who are not interested in football, we can use the following formula:

Number of residents not interested in football = Total population of the city * Percentage of residents not interested in football

Number of residents not interested in football = 80,000 * 0.4 = 32,000

Therefore, there are 32,000 residents in the city who are not interested in football.

Step 3: Calculate the Number of Football Fans

To calculate the number of football fans, we need to subtract the number of residents who are not interested in football from the total population of the city:

Number of football fans = Total population of the city - Number of residents not interested in football

Number of football fans = 80,000 - 32,000 = 48,000

Therefore, there are 48,000 football fans in the city.

Step 4: Calculate the Number of Football Fans Who Watched the Champions League Final on TV

According to the information provided, 75% of the football fans watched the Champions League final on TV. To calculate the number of football fans who watched the final on TV, we can use the following formula:

Number of football fans who watched the final on TV = Number of football fans * Percentage of football fans who watched the final on TV

Number of football fans who watched the final on TV = 48,000 * 0.75 = 36,000

Therefore, 36,000 residents of the city watched the Champions League final on TV.

In conclusion, 36,000 residents of the city watched the Champions League final on TV.
