The rate of change in sales for a candle company from 1998 through 2005 can be modeled by {eq}displaystyle frac{ds}{dt} = 0.521t +frac{ 597.2093}{t}{/eq} where {eq}s{/eq} is the sales (in millions) and {eq}t = 8{/eq} corresponds to 1998. In 1999, the sales for the candle were {eq}256.2{/eq} million.

a) Find a model for sales from 1998 through 2005 places).
(Round your constant term to two decimal places)
b) Find the candle company’s sales in 2001 in millions.
