Calculating Percentage Increase in Subscribers for "Zapad" Internet Company

To calculate the percentage increase in the number of subscribers for the "Zapad" internet company, we can use the following formula:

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

Given: - Old Value (beginning of the year): 400,000 subscribers - New Value (end of the year): 420,000 subscribers

Using the formula: Percentage Increase = ((420,000 - 400,000) / 400,000) * 100

Calculation

The percentage increase in the number of subscribers for the "Zapad" internet company is calculated as follows: Percentage Increase = ((420,000 - 400,000) / 400,000) * 100 = (20,000 / 400,000) * 100 = 0.05 * 100 = 5%

Therefore, the number of subscribers for the "Zapad" internet company increased by 5% during the year.
