Answer 1

To calculate the total cost of the cell phone bill for the years 2009-2018, multiply the average cost each year by 1.092 to find the cost for the following year. Repeat this process for each year and add up the costs to find the total.

Step-by-step explanation:

To calculate the total cost of the cell phone bill for the years 2009-2018, we can use the given information about the average cost each year. We know that the average cost each year is about 109.2% of the previous year, so we can use this to calculate the cost for each year.

For 2009, the cost is $650. To find the cost for 2010, we multiply $650 by 109.2% (1.092) to get $709.80. Similarly, for 2011, we multiply $709.80 by 1.092 to get $774.19. We continue this process for each year until 2018.

Adding up the costs for each year from 2009 to 2018 will give us the total cost for the cell phone bill during that period.
