To find out how many customers the internet service provider currently has, we start with last year's total and add this year's net gain:
Total customers this year = Last year's customers + Net gain this year Total customers this year = 17,156 + 1,802 = 18,958
Next, to find out how many more customers they need to reach their goal of at least 35,000 customers in ten years:
Customers needed = Goal - Current customers Customers needed = 35,000 - 18,958 = 16,042
Therefore, they need approximately 16,042 more customers to reach their goal.
