You decide to take care of the major cost first–hall rental and caterer. Each caterer you approach is associated with a specific hall.

Caterer 1 charges $45 per person. The cost of using the hall is inclusive.

Caterer 2 charges $250 for hall rental plus $28 per person.

Caterer 3 charges $500 for hall rental plus $20 per person.

Write equations to represent the cost of each caterer based on the number of people. Use the variable y to represent the cost, and the variable x to represent the number of people attending the event.
