Question 974693
Let {{{ A }}} = the current amount in
the bank accounts
Let {{{ w }}} = number of weeks passed
(1) {{{ A = 85 + 15w }}}
(2) {{{ A = 610 - 10w }}}
------------------------
The break even point is where the two
accounts are equal
{{{ 85 + 15w = 610 - 10w }}}
{{{ 25w = 525 }}}
{{{ w = 21 }}}
In 21 weeks, their accounts are equal
