Calculation of the Number of City Residents Who Watched the Final of the Gagarin Cup on TV

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

1. Determine the total number of city residents who are not interested in hockey. 2. Calculate the number of city residents who are interested in hockey. 3. Calculate the percentage of hockey fans who watched the final on TV. 4. Multiply the number of hockey fans by the percentage who watched the final on TV to find the final answer.

Let's go through each step in detail:

Step 1: Determine the total number of city residents who are not interested in hockey.

According to the given information, 80% of the city's 120,000 residents are not interested in hockey. To find the number of residents who are not interested in hockey, we can multiply the total number of residents by the percentage who are not interested:

Number of residents not interested in hockey = 120,000 * 0.8

Step 2: Calculate the number of city residents who are interested in hockey.

To find the number of residents who are interested in hockey, we can subtract the number of residents not interested in hockey from the total number of residents:

Number of residents interested in hockey = 120,000 - (120,000 * 0.8)

Step 3: Calculate the percentage of hockey fans who watched the final on TV.

According to the given information, 85% of hockey fans watched the final of the Gagarin Cup on TV. To find the percentage of hockey fans who watched the final on TV, we can multiply the percentage by 0.01:

Percentage of hockey fans who watched the final on TV = 85 * 0.01

Step 4: Multiply the number of hockey fans by the percentage who watched the final on TV.

To find the number of city residents who watched the final of the Gagarin Cup on TV, we can multiply the number of residents interested in hockey by the percentage of hockey fans who watched the final on TV:

Number of residents who watched the final on TV = (Number of residents interested in hockey) * (Percentage of hockey fans who watched the final on TV)

Now, let's calculate the final answer:

Number of residents not interested in hockey = 120,000 * 0.8 = 96,000 Number of residents interested in hockey = 120,000 - 96,000 = 24,000 Percentage of hockey fans who watched the final on TV = 85 * 0.01 = 0.85 Number of residents who watched the final on TV = 24,000 * 0.85 = 20,400

Therefore, 20,400 residents of the city watched the final of the Gagarin Cup on TV.
