Hank is throwing a surprise party. the party costs $20 per person. create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.

the equation can be used to represent this relationship.

c = 20f
f = 20c
c = 10f
f = 10c

well, the costs equals $20 per person (or "friend")

so it would be c=20f
