The equation is
[tex] w=241(1.06)^t [/tex]
And here variable t represents the number of years since 2000.
In 2001 means t=2001 -2000 = 1
So we plug 1 for t in the given expression , that is
[tex] w =241(1.06)^1 = 241*1.06 = 255.46 [/tex]
Therefore in 2001, it should be worth to 255.46.
And in the given expression 1.06=1 +0.06, where 0.06 is the annual percent of growth that is 6 % .
