Answer 2

Calculation of Cost Savings

To calculate the number of working days required for the replacement of metro travel with a moped to become cost-effective, we need to consider the cost of metro travel and the cost of using a moped.

According to the information provided, the cost of metro travel for Lyudmila is 30 rubles for a one-way trip. Therefore, the round trip cost would be 60 rubles.

The cost of a moped is given as 100,000 rubles, and the daily cost of fuel for the moped is 10 rubles.

To determine the number of working days required for the moped to become cost-effective, we need to calculate the difference in cost between using the metro and using the moped.

Let's calculate the cost of using the moped for a day: - Cost of fuel per day: 10 rubles

Now, let's calculate the cost of using the metro for a day: - Round trip cost of metro travel: 60 rubles

To find the difference in cost, we subtract the cost of using the moped from the cost of using the metro: - Difference in cost: 60 rubles - 10 rubles = 50 rubles

Therefore, by using a moped instead of the metro, Lyudmila would save 50 rubles per working day.

To determine the number of working days required for the moped to become cost-effective, we divide the cost of the moped by the daily cost savings: - Number of working days required: 100,000 rubles / 50 rubles = 2000 working days

Therefore, Lyudmila would need to use the moped for 2000 working days for the replacement of metro travel with a moped to become cost-effective.

The numerical value for the number of working days required for the replacement of metro travel with a moped to become cost-effective is 2000.
