Question 3:

Hank is throwing a party. The party costs $20 per person. Answer the questions below to describe the relationship between the cost of the party and the number of friends attending.

The independent variable is Number of friends (f) Cost of party (c) .

The dependent variable is Number of friends (f) Cost of party (c) .

The equation that can be used to represent this relationship: c = 20f f = 20c c = 10f f = 10c

If 50 people attended, what would be Hank's cost?
(Only input numeric values, no commas, decimal points, or symbols.)

The equation that could be used to represent this relationship is... c = 20f

If 50 people attended, Hanks cost would be... $1000... because...
- c = 20 x 50
- 1000 = 20 x 50
So, it will be $1000 for the party, if 50 people come to the party.

Answer:

Party will cost $1000 to Hank

Step-by-step explanation:

Hank is throwing a party.

Cost of the party = $20 per person

Let the number of friends who will attend the party = f

And cost of the party with f friends = c

Then relation between cost and friends will be represented by the equation

c = 20f

If 50 friends are attending the party then cost of the party = 20×50

= $1000

Therefore, party will cost $1000 to Hank.
