A fund earning 4% effective has a balance of $1,500 at the beginning of the year. If$100 is added to the fund at the end of three months and if $700 is withdrawn from the fund at the end of nine months, find the ending balance under the assumption a(1)/a(t) = 1 + ( 1 - t )i help i have this finance assignment due....and the answer i got does not seem to be right at all...can someone help me thanks 2. ## Reply If you were searching for this ; After three months, the funds are 1500*1.04^3/12=1515$.
Then you add 100$. You're at 1515$ + 100$= 1615$.
Then 1615*1.04^6/12=1647$. And you substract 700$.
