Calculation of Percentage Increase in Ticket Price

To calculate the percentage increase in the ticket price for a single trip on the Moscow Metro between May 15, 1998, and May 15, 2008, we can use the following formula:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Let's plug in the values:

Old Value (May 15, 1998) = 2 rubles New Value (May 15, 2008) = 19 rubles

Percentage Increase = ((19 - 2) / 2) * 100

Calculating this, we find that the ticket price for a single trip on the Moscow Metro increased by 850% from May 15, 1998, to May 15, 2008.
