Calculation of the Cost of Travel

To calculate the cost of travel for 4 adults and 12 schoolchildren, we need to consider the following information:

- The cost of travel in an electric train is 198 rubles. - Schoolchildren receive a 50% discount on the fare.

Let's calculate the cost step by step:

1. Calculate the cost for 4 adults: - The cost for 1 adult is 198 rubles. - Multiply the cost for 1 adult by the number of adults (4): 198 rubles * 4 = 792 rubles.

2. Calculate the cost for 12 schoolchildren: - The cost for 1 schoolchild is 50% of the adult fare, which is 198 rubles * 0.5 = 99 rubles. - Multiply the cost for 1 schoolchild by the number of schoolchildren (12): 99 rubles * 12 = 1188 rubles.

3. Calculate the total cost: - Add the cost for adults and schoolchildren: 792 rubles + 1188 rubles = 1980 rubles.

Therefore, the total cost of travel for 4 adults and 12 schoolchildren would be 1980 rubles.
