You are planning a party on a limited budget. In order to do so you will need to determine how much it will cost to rent a space and pay per person for meals. If the cost of the rental space is $780 and the price per person for food is $9.75, how much would it cost to host 50 people for the party? In your post please write a linear equation in the form of y = mx + b to model the scenario. Then, show the cost for 50 people.
