Calculation of the Cost of Travel for a Group of Adults and Schoolchildren

To calculate the cost of travel for a group consisting of 12 adults and 8 schoolchildren, we need to consider the discounted fare for schoolchildren and the regular fare for adults.

The regular fare for the suburban electric train is 180 rubles However, schoolchildren are eligible for a 50% discount on the fare

To calculate the cost of travel for the group, we can follow these steps:

1. Calculate the cost of travel for the adults: - Number of adults: 12 - Regular fare per adult: 180 rubles - Total cost for adults: 12 adults * 180 rubles/adult = 2160 rubles

2. Calculate the cost of travel for the schoolchildren: - Number of schoolchildren: 8 - Discounted fare per schoolchild: 50% of the regular fare (180 rubles) - Total cost for schoolchildren: 8 schoolchildren * (50% * 180 rubles/schoolchild) = 720 rubles

3. Calculate the total cost of travel for the group: - Total cost for adults: 2160 rubles - Total cost for schoolchildren: 720 rubles - Total cost for the group: 2160 rubles + 720 rubles = 2880 rubles

Therefore, the cost of travel for a group consisting of 12 adults and 8 schoolchildren in the suburban electric train is 2880 rubles.
