Let’s check out your problem:

Dina is conducting a study on the amount of electricity used per person in the country of Qatar. She finds that from the year $2000$ to $2008$ , the amount of electricity used per person grew by an average of $6 \%$ from one year to the next.$\newline$Let $E(t)$ be the amount of electricity used per person in kilowatt-hours and $t$ be the number of years after $2000$ . If the amount of electricity used per person in $2000$ was approximately $12$,$300$ kilowatt-hours, which of the following mathematical models will give Dina how much electricity was used per person between $2000$ and $2008$ ?$\newline$Choose $1$ answer:$\newline$(A) $E(t)=12,300 \cdot(1.06)^{t}$$\newline$(B) $E(t)=12,300 \cdot(0.06)^{t}$$\newline$(C) $E(t)=12,300+(1.06) \cdot t$$\newline$(D) $E(t)=12,300+(0.06) \cdot t$
