Question 915647
The debt is paid in:
{{{ 200/12 = 50/3 }}} weeks
--------------------------
It takes
{{{ 60/12 = 5 }}} weeks to pay off $60
{{{ 50/3 - 5 = 50/3 - 15/3 }}}
{{{ 35/3 = 11.667 }}}
-------------------
Let {{{ A }}} = amount owed
Let {{{ w }}} = weeks that debt is paid
--------------------------------
{{{ A = 200 - 12w }}}
{{{ A < 60 }}}
{{{ 200 -12w < 60 }}}
{{{ 12w > 200 - 60 }}}
{{{ 12w > 140 }}}
{{{ w > 35/3 }}}
{{{ w > 11.667 }}}
You will owe less than $60 when you
are 2/3 of the way through the 12th week
