Answer:
Party will cost $1000 to Hank
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.
