Question

Robert wants to throw a party for his friends. He has booked a banquet hall where he plans to serve dinner. The hall costs $200, and dinner costs $30 per person. If the final bill is p, which function gives the number of friends at the party. [Hint: First find the function for the final bill as a function of the number of friends, x.]

Answer 1

Your standard equation is y = mx + b

P should be the output (y) because it is the final bill. B should be represented by 200 because the $200 is an additional, once payed fee. M should be 30 because the amount payed for dinner depends on how many people are served.

p = final bill
b = 200
m = 30
x = number of friends

So, your equation would look like p = 30x + 200

Hope this helps!

Answer 2

Answer:

(p-200)/30 that is the answer good luck
