Answer 1

Approximately 170 million units of the item will be sold in 2025.

Step-by-step explanation:

To predict the number of units sold in 2025, we can use the trend in sales from 2004 to 2008. In 4 years, the sales increased from 10 million units to 50 million units. This means there was an increase of 40 million units in 4 years. So, the average increase per year is 40 million units divided by 4, which is 10 million units per year.

From 2008 to 2025, there are 17 years. Therefore, we can estimate that the number of units sold in 2025 will increase by 10 million units per year for 17 years.

10 million units per year times 17 years is 170 million units. Therefore, approximately 170 million units of the item will be sold in 2025.
