a) Jasmine makes quarterly deposits of $1,000 into a savings account that pays 4 percent compounded monthly. How much money will she have in her account in 25 years?
A.
Quarterly deposits = $1000
Effective quarterly rate R = (1+4%/12)^3 - 1 = 1.0033%
Number of quarters in 25 years = 100
So,
Future value of deposits after 25 years = 1000*(1.010033^100 - 1)/.010033
Future value of deposits after 25 years = $170802.92 or $170803
So, value of deposits in 25 years is $170802.92 or $170803.

B.
A.
Monthly deposits = $1000
Effective monthly rate R = (1+4%/4)^(1/3) - 1 = .3322%
Number of months in 25 years = 300
So,
Future value of deposits after 25 years = 1000*(1.003322^300 - 1)/.003322
Future value of deposits after 25 years = $513119.96 or $513120
So, value of deposits in 25 years is $513119.96 or $513120.

A.
It is a case of annuity due as payment takes place in the beginning of the month.
Monthly deposits = $1000
Monthly rate = 4%/12
Number of months in 25 years = 300
So,
Future value of deposits after 25 years = (1000*((1+4%/12)^300 - 1)/(4%/12))*(1+4%/12)
Future value of deposits after 25 years = $515843.3 or $515843
Hence , value of deposits in 25 years would be $515843.3 or $515843.
