Question 1068251
$20 per ticket;
x tickets;
$1800 rent of supplies;
$6 per plate.
ALSO x plates.  This is only assuming one to one ticket to plate.


Cost for school:
{{{1800+6x}}}


Revenue for school:
{{{20x}}}


They hope to raise at least $50000 for the dinner.
This seems to mean, the profit hoped-for is 50000.
{{{highlight_green(20x-(6x+1800)>=50000)}}}.


The question should be, "What is an equation or inequality for the number of tickets the school should sell."
