The correct formula is
C(t) =C(a)^k/t
where C(t) is the cost after k years, C is the present cost, a= 3,
t = 10 years and k =16 years
subbing these values in the formula, we get
C(t) = $75(3)^16/10
=$435 (Rounded to the nearest $)
A(t) =Ca^kt ? Is it a standard formula? What are A, C, a k and t any way? YOu did not give the meaning of these symbols at all.
