1.future value of single amount invested = amount invested*(1+r)^n

here,

future value =$1969.32

amount invested =520

r= to be found out.

n=10.

=>1969.32 = 520*(1+r)^10

=>(1+r)^10 = 3.78715384615

=>(1+r)=> (3.78715384615)^(1/10)

=>1+r=1.14243445

=>r=0.14243446

=> rate of interest = 14.24%.
