Answer:
273.48 tenths of years
Step-by-step explanation:
This is a Time Value of Money (TVM)First, convert the annual interest rate to a tenth of a year rate;
= 7% *(1/10) = 0.7%
Interest rate ; I/Y = 0.7%
Present value; PV = -8000
Future value ; FV = 53900
Recurring payment; PMT = 0 (since this is not an annuity)
then compute the duration; CPT N = 273.48 tenths of years
