Annual Sales (in millions of units) of PC are expected to grow in accordance with the rate of f(t)=0.18t^2 + 0.16t + 2.64 ; (0<=t<=6) where t is measured in years with t=0 corresponding to year 1997. How many PC will be sold over the 6 year period between the beginning of 1997 and the end of 2002?

Since years are represented by "t," the amount of years, or "t," from beginning of 1997 and end of 2002 is 6.

Substituting 6 for "t" in the equation, we get: ---- ---- ---- f(6), or over a 6-year period, million units will be sold.
