The number of computers a certain computer store sold since 2005 can be modeled by
the function N (t) = 5t + 106 and the price per computer can be modeled by
P(t) = 13t? – 25t + 600, where t is the number of years since 2005.
According to this model, what is the total amount of revenue generated by the
computer store's sales in 2011?
Your answer should be a specific dollar amount.
