The realtionship between force of interest
(k) and accumulation function a(t) is given by
a(t) = e
Let us assume that
(t) is a constant function say,
(t) = c, for all t where c is the constant.
a(t) = e
a(t) = e
Then, a(t) = ect since (
= s[t] - s[0] = t - 0 = t)
Solving we have
(t) = ln(1.5) for all non negative 't'
This implies that a(t) = e[ln(1.5)]^t
a(t) = 1.5t
Solving for the given case where t = 4, we get a(t) = 5.0625
Option (A)
