Question

Аня купила проездной билет на месяц и сделала за месяц 55 поездок. Сколько рублей она сэкономила, если проездной билет стоит 400 рублей, а разовая поездка составляет 2,5% от стоимости проездного билета?

Answer 1

Складаємо пропорцію:
400×2,5\100 = 10 рублів
за 55 поїздок їй потрібно заплатити 10 × 55 = 550 рублів
550 - 400 = 150 рублів вона зекономила

Answer 2

Calculation of Savings on Monthly Pass

To calculate the amount of money Anna saved by purchasing a monthly pass and making 55 trips within a month, we need to determine the cost of individual trips and compare it to the cost of the monthly pass.

Given: - Cost of the monthly pass: 400 rubles - Each individual trip costs 2.5% of the monthly pass price

To find the cost of each individual trip, we can calculate 2.5% of 400 rubles: 2.5% of 400 rubles = 0.025 * 400 rubles = 10 rubles

Therefore, each individual trip costs 10 rubles.

Now, let's calculate the total cost of 55 individual trips: Total cost of 55 trips = 55 trips * 10 rubles per trip = 550 rubles

To find the amount Anna saved, we subtract the total cost of individual trips from the cost of the monthly pass: Amount saved = Cost of monthly pass - Total cost of individual trips Amount saved = 400 rubles - 550 rubles = -150 rubles

Based on the calculations, Anna did not save any money by purchasing the monthly pass. In fact, she spent an additional 150 rubles compared to paying for each trip individually.
