To calculate cell phone usage this year, add 70% of last year's usage to last year's total. The residents of Belleville used their cell phones for 1,444,779 minutes this year.

Step-by-step explanation:

The question requires us to calculate how many minutes Belleville residents used their cell phones this year. Eddie found out that residents of Belleville used their cell phones for 849,870 minutes last year and that this year they used them 70% more.

To find the total minutes used this year, we first calculate 70% of last year's minutes: 849,870 * 0.70 = 594,909 minutes.

We then add this amount to last year's total to obtain this year's total usage: 849,870 + 594,909 = 1,444,779 minutes. Therefore, the residents of Belleville used their cell phones for 1,444,779 minutes this year.
