Answer:
Let f be the number of friends
Let c be the cost of the party
As (f) is the independent variable, the number of friends will be along the x-axis.
As (c) is the dependent variable, the cost of the party will be along the y-axis.
If the cost of the party is $20 per person, then the equation to represent the relationship is:
c = 20 f
