Question 1109005
{{{ I = P*r*t }}}
{{{ P = 1100 }}}
{{{ I = 1127.12 - 1100 }}}
{{{ I = 27.12 }}}
{{{ r = .045 }}}
-----------------
{{{ 27.12 = 1100*.045*t }}}
{{{ 27.12 = 49.5t }}}
{{{ t = .547878 }}}
{{{ .547878*365 = 199.976 }}}
The deposit was made 200 days before Oct 13
Jan - 31 days

Apr = 30 days
May - 31 days
Jun - 30 days
Jul - 31 days
Aug - 31 days
Sept - 30 days
Oct  - 13 days
-----------------
Apr 1 through Oct 13 is:
{{{ 13 + 30 + 31 + 31 + 30 + 31 + 30 = 196 }}}
So, I need 4 days from March
{{{ 31 - 4 = 27 }}}
