Answer:
About 31 years 
Step-by-step explanation:
Given data
Principal= $3500
Rate=  4.75% 
Final amount= $15,000
Time=??
The expression for time on compound interest is 
Calculate time, solve for t
t = ln(A/P) / r
substitute
Calculate time, solve for t
t = ln(15000/3500) / 0.0475
t= ln(4.2857)/ 0.0475
t= 1.4552/0.0475
t= 30.63 years
Hence it will take about 31 years
