Answer: 4095

<u>Step-by-step explanation:</u>

He sold 1 car on the first day so the first term (a) is 1. The amount doubles each month so the ratio (r) is 2.

Input those values into the Sum formula:

$S_n=\dfrac{a(1-r^n)}{1-r}\\\\S_{12}=\dfrac{1(1-2^{12})}{1-2}\\\\.\quad=\dfrac{1-4096}{-1}\\\\.\quad=\dfrac{-4095}{-1}\\\\.\quad=4095$
