Question 61862
I'll try
{{{P= A/(1+r/n)^nt}}}
{{{P = 250000 / (1 + .07/4)^(4*30)}}}
{{{P =  25*10^4 / (4.07/4)^120}}}
{{{log(P) = log(25*10^4 / (4.07/4)^120)}}}
{{{log(P) = log(25) + log(10^4) - log(1.0175^120)}}}
{{{log(P) = 1.398 + 4 - 120*(.00753)}}}
{{{log(P) = 5.398 - .904}}}
{{{log(P) = 4.494}}}
{{{P = 10^4.494}}}
{{{P = 31188}}}
The deposit should be $31,188
Unless my calculator or I made an error
