Answer: $6,018.26
Explanation: From the question above, we are calculation the present sum to be invested and it is calculated thus:
A=P(1+r/n)^nt
6,500= P(1+0.026/1)^1*3
6,500=P(1.026)^3
6,500=P(1.080045576)
P=6,500/1.080045576
P=6,018.26
P=$6,018.26
The Initial lump sum savings amount is $6,018.26
