6 A Periodic Deposit Is Made Into An Annuity With The Given Terms Find How Much Should Be Regularly Deposited In Order To Have The Specified Final Amount In The class=

Sagot :

Remember that

The formula for the future value of an ordinary annuity is equal to:

[tex]FV=P\lbrack\frac{(1+ \frac{r}{n} )^{nt} -1}{ \frac{r}{n} }\rbrack[/tex]

where

FV is the future value

P s the periodic payment

r is the interest rate in decimal form

n is the number of times the interest is compounded per year

t is the number of years

In this problem we have

FV=$122,000

r=2.45%=0.0245

n=12

t=17 years

P=?

substitute the given values

[tex]122,000=P\lbrack\frac{(1+\frac{0.0245}{12})^{(12\cdot17)}-1}{\frac{0.0245}{12}}\rbrack[/tex]

solve for P

P=$482.72 ------> round to the nearest dollar

P=$483
