C'=1.5
c/c'=d/d'
c/1.5=8
c=12
hope that helps :)
So in 6 months (1/2yr) you earned $15.75 interest, if we double that we find the total interest you would gain for that year, 15.75x2= $31.5 total interest for that year.
To find the annual rate divide the interest gained by the amount deposited, 31.5/500 = 0.063% p.a.
