Question 1046204
Let {{{ n }}} = number of weeks they are saving
Let {{{ A }}} = amount saved
Anisa's equation:
{{{ A = 35.5 + 4.25n }}}
Nadia's equation:
{{{ A = 24.25 + 5.5n }}}
----------------------
Set amounts saved equal to eachother
{{{ 35.5 + 4.25n = 24.25 + 5.5n }}}
{{{ 1.25n = 11.25 }}}
{{{ n = 9 }}}
In 9 weeks they will have the same amount
-------------------
check:
{{{ A = 35.5 + 4.25*9 }}}
{{{ A = 35.5 + 38.25 }}}
{{{ A = 73.75 }}}
and
{{{ A = 24.25 + 5.5*9 }}}
{{{ A = 24.25 + 49.5 }}}
{{{ A = 73.75 }}}
OK
