A=final amount
P=initial amount invested
r=rate in decimal form
n=number of times compounded per year
t=time in years
given
A=4900
P=4200
r=r (we are solving for this)
n=semianually=2 times per year
t=4
find r
divide both sides by 4200
take 8th root of both sides
minus 1
multiply both sides by 2
r=0.038911
r=3.891% so about 3.89%
