A bike rental company rented out 6 bikes in its first month. The number of bikes it rented tripled each month.What was the total number of bikes the company rented out for the first 6 months?
Question
Answer:
Hi there! The total number of bikes rented is 2,184
If you plug in the correct numbers into the formula
[tex]a \dfrac{1- r^{n} }{1-r} [/tex]
Then you get
[tex]6 \dfrac{1- 3^{6} }{1-3} [/tex]
And when the fraction is simplified it looks like this
[tex]6 \dfrac{-728}{-2} [/tex]
Once this is in simplified form you take the 6 and put it over 1 like so
[tex] \dfrac{6}{1} * \dfrac{-728}{-2}[/tex]
Then you find the prime factors of 6 and factor the -2 like so
[tex] \dfrac{3*2}{1} * \dfrac{-728}{-1*2}[/tex]
Once this is done cancel out the 2
[tex] \dfrac{3}{1} * \dfrac{-728}{-1}[/tex]
Then multiply -728 by 3
[tex]\dfrac{-2184}{-1}[/tex]
Then divide to get 2184
