A 4-column table with 4 rows. Column 1 is labeled f with entries 3, 5, 7, 9. Column 2 is labeled 15.5 + 12 f with blank entries. Column 3 is labeled c with blank entries. Column 4 is labeled (f, c) with blank entries. Gale thought that it would be fun to go to the carnival. The carnival cost $15.50 for the first person and $12.00 for each additional person.

Equation: c = 15.5 + 12f

c = cost

f = number of friends

If the input of the equation is 3, what is the output?

51.5 or 51.50

They both will work!

Step-by-step explanation:

Gale thought that it would be fun to go to the carnival. The carnival cost $15.50 for the first person and $12.00 for each additional person.  

Equation: c = 15.5 + 12f  So this is the equation which is telling you what you have to and were to input the info you need.

c = cost  

f = number of friends

If the input of the equation is 3, what is the output?  This is telling you to put the in place of the F because there are 3 friends.

Now after you have done that your equation should look like this

c = 15.5 + 12(3)

Now the number in the parenthesis is the number you have to times by 12 so if you times 12 by 3 you would get 36 then you would add 36 and 15.5 together which would give you 51.5. 51.5 is the answer to the question! I hope you understand and if you need further help please comments and i should get to you in about a day unless its the weekends! By!
