**helper**, Friday, February 11, 2011 at 1:13pmIn 1995--64.8 yrs

In 1999--67.2 yrs

To write the equation, use the points

1999 - 1995 = 4 yrs

1995--(0, 64.8)

1999--(4, 67.2)

Equation through two points,

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)

y - 64.8 = (67.2 - 64.8)/(4 - 0) * (x-0)

y - 64.8 = 2.4/4 x

y - 64.8 = 0.6x

y = 0.6x + 64.8

Since, the function should be E(t),

E(t) = 0.6t + 64.8

To find E(t) for 2006,

E(11) = 0.6(11) + 64.8

E(11) = ?
