Final answer:
To determine the cost of the party, multiply the cost of renting the room by the number of people and the cost of food per person by the number of people. Then, add the two costs together.
Step-by-step explanation:
To calculate the cost of the party, you need to multiply the cost of renting the room ($35) by the number of people you are bringing to the party (8). Then, you need to multiply the cost of food per person ($4) by the number of people (8). Finally, add the two costs together to get the total cost of the party.
Cost of renting the room: $35 x 8 = $280
Cost of food per person: $4 x 8 = $32
Total cost of the party: $280 + $32 = $312
So, it will cost $312 if you bring 8 people to the party.
