Payments of $6,000.00 are made into a fund at the beginning of each year for ten years. The fund is invested at an annual effective rate of i. The interest generated is reinvested at 10%. The total accumulated value at the end of the ten years is $98,180.00. Find I round to 3 decimal places
Given
Payment each year P=6000
Number of payment N=10
Interest in first account =i
interest in second account r=10%
AV=98180
AV=AV1+AV2
Since interet is reinvested each year in another account so accumultaed amount in first account = Sum of all deposit
AV1=10*6000=60000
98180=60000+AV2
AV2=38180
Future value of interest = Interest *(1+r)^(10-n)
Since interest is reinvested at end of each year so in year ZERo there will be no interest.
