How much must be deposited today into the following account in order to have $35,000 in 7 years for a down payment on a​ house?
Rom4ik [11]

Answer:

The amount that must be deposited is $ 19973.87.

Step-by-step explanation:

We have a relation between future value present value as:

                                       F= P (1 +\frac{r}{n}  )^{nt}

F=future value

P=present value

r=rate (as a decimal)

n=number of compounding periods per year

t=number of years

Now,

               assume rate as 8%

                                       35000= P (1+\frac{0.08}{12} )^{12*7}

                                or,   35000= P × 1.0067^{84}

                                      or, P = \frac{35000}{1.7522}

                                     or, P = $ 19973.87

So you must deposit $ 19973.87 today.
