Question 344949
OK, you've got one equation. 
What about the rest of the information you've been given??
{{{(1/4)W=(1/6)F}}}
{{{W=(4/6)F}}}
{{{W=(2/3)F}}}
.
.
.
Now substitute that into your first equation.
{{{W+F=80000}}}
{{{(2/3)F+F=80000}}}
Now solve for {{{F}}}.
Then go back and solve for {{{W}}}.
