11. the student council is comparing prices for their semi-formal dance. they compare banquet. hall A charges $40 per person. hall B charges $20 per person plus $500 fixed fee. write an equation to represent the relationship between the total cost and the number of people, if the variables are defined as follows: let n represent the number of people attending. let c represent the total cost.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
