Question

A bike rental company rented out 6 bikes in its first month. The number of bikes it rented tripled each month.

Answer 1

Hi there! 

The total number of bikes rented is 2,184

If you plug in the correct numbers into the formula 

$a \dfrac{1- r^{n} }{1-r}$

Then you get

$6 \dfrac{1- 3^{6} }{1-3}$

And when the fraction is simplified it looks like this

$6 \dfrac{-728}{-2}$

Once this is in simplified form you take the 6 and put it over 1 like so

$\dfrac{6}{1} * \dfrac{-728}{-2}$

Then you find the prime factors of 6 and factor the -2 like so

$\dfrac{3*2}{1} * \dfrac{-728}{-1*2}$

Once this is done cancel out the 2

$\dfrac{3}{1} * \dfrac{-728}{-1}$

Then multiply -728 by 3

$\dfrac{-2184}{-1}$

Then divide to get 2184
