A caterer charges a flat fee to put on an event, plus a per person cost based on how many people attend. Suppose the flat fee is $2500 and the per person cost is $75. A different caterer charges a $3000 fee and $50 per person. Model these two situations with graphs and equations. Which caterer is a better deal for the customer?
