Question 720752
Let {{{ x }}} = number of adults served
{{{ 500 - x }}} = number of children served
given:
{{{ 7x + 4.5*( 500 - x ) }}}
{{{ 7x + 2250 - 4.5x }}}
Money raised = {{{ 2.5x + 2250 }}}
Here's the plot for this with money
raised on the vertical axis and
{{{x }}} on the horizontal axis
{{{ graph( 400, 400, -100, 600, -500, 5000, 2.5x + 2250 ) }}}
