The average cell phone bill per year was $650 in 2009. if the average cost each year is about 109.2% of the previous year (9.2% increase), what will a person pay total for a cell phone for 2009-2018? (round to nearest dollar.) question 9 options: $8535 $6500 $7098 $9970 save

$ 8535

Step-by-step explanation:

Given,

The average cell phone bill in 2009 = $ 650,

Since, the average cost each year is about 109.2% of the previous year,

Thus, there is a GP, that shows the average cell phone bill of every year,

That having first term, a = 650,

Common difference, d = 109.2 % = 1.092,

Thus, the total cell phone bill for 2009-2018 = Sum of the 9 terms of the above G.P.

Hence, The person will pay approximately $ 8535 for 2009 - 2018.

First option is correct.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
