You can put this solution on YOUR website!
Let +x+ = number of adults served
+500+-+x+ = number of children served
given:
+7x+%2B+4.5%2A%28+500+-+x+%29+
+7x+%2B+2250+-+4.5x+
Money raised = +2.5x+%2B+2250+
Here's the plot for this with money
raised on the vertical axis and
x+ on the horizontal axis
+graph%28+400%2C+400%2C+-100%2C+600%2C+-500%2C+5000%2C+2.5x+%2B+2250+%29+
