An internet service provider had a total of 17,156 customers last year. They gained a net of 1,802 customers this year. They hope to reach at least 35,000 customers in ten years. Estimate the number of customers they need to reach their goal.??????/

To estimate the number of customers the internet service provider needs to reach their goal, we need to consider their current number of customers and the rate at which they are gaining customers each year.

First, let's calculate the current number of customers for next year:
Current number of customers + Net gain of customers = 17156 + 1802 = 18958 customers

Now, let's estimate the number of customers for each year based on the net gain of 1802 customers per year:
Year 1: 18958 + 1802 = 20760 customers
Year 2: 20760 + 1802 = 22562 customers
Year 3: 22562 + 1802 = 24364 customers
Year 4: 24364 + 1802 = 26166 customers
...
Year 10: (Number of customers after 9 years) + 1802 = 35000 customers

To estimate the number of customers they need to reach their goal of 35000 customers in 10 years, we need to find the number of customers after 9 years, which is 35000 - 1802 = 33198 customers.

Therefore, the internet service provider needs to reach approximately 33,198 customers to reach their goal.
