The number of dislocated electric impulses per cubic inch in a transformer increases when lightning strikes by $\mathrm{D}=6600(2)^{\mathrm{x}}$, where $\mathrm{x}$ is the time in milliseconds of the lightning strike. Find the number of dislocated impulses at $\mathrm{x}=0$ and $\mathrm{x}=5$.
A) 13,$200 ; 211,200$
B) $6600 ; 66,000$
C) $6600 ; 211,200$
D) $6600 ; 26,400$

At $x=0$, $D=6600(2)^0=6600(1)=6600$. At $x=5$, $D=6600(2)^5=6600(32)=211,200$.
