The goal is to find the percentage increase in the number of subscribers in the 'Elder' category from 2023 to 2024.
First, let's summarize relevant information:
- Total subscribers increased by 10% from 2023 to 2024.
- In 2023, 'Elder' using multiple apps = 15,000.
- In 2023, 'Kid' using one app = 10,000, equal to 'Elder' using one app.
Let total subscribers in 2023 be
x.
Total subscribers in 2024 = 1.1
x.
Step 1: Calculate 2023 Elder SubscribersSubscribers from 'Elder' (one app) = 10,000 (from given data).
Subscribers from 'Elder' (multiple apps) = 15,000 (from given data).
Total 'Elder' subscribers in 2023 = 10,000 + 15,000 = 25,000.
Step 2: Find Total Subscribers in 2023Since 'Elder' using one app is equal to 'Kid' (10,000), we know 'Elder' using one app in 2023 is 22.5% of total subscribers. Let total subscribers in 2023 be
x.
0.225
x = 10,000
x = 10,000 / 0.225 = 44,444.44
Step 3: Calculate Total Elder Subscribers in 2024Total subscribers in 2024 = 1.1
x = 1.1 × 44,444.44 = 48,888.88
In 2024, 'Elder' subscribers form approximately 30% of total [as indicated by bar graph assumption].
Total 'Elder' = 0.3 × 48,888.88 = 14,666.664
Step 4: Calculate Percentage IncreaseDifference in 'Elder' subscribers from 2023 to 2024 = 14,666.664 - 25,000 = 19,333.33.
Percentage increase = ((19,333.33 / 25,000) × 100) % = 65%.
Thus, the percentage increase is
65%.
