Question

The function rule C= 10n+26 relates the number of people n who attend a small concert to the cost in dollars C of the concert. Make a table of the input/output pairs to show the cost if 27,39, and 43 people attend.

Answer 1

n: C=10n+26
------------------
27: 10(27)+36 = 270+36 = 306
and so on with the other values

Answer 2

@Steve
If you don't mind me asking, how did you come up with the number 36 for n when 26 is for n? My results to this problem is:

C = 10n + 26
n = 27
10*27 = 270
270 + 26 = 296

(n)27/(C)296

As for the user @stupid at math, I would recommend to keep following this pattern to find the next few values to your table your creating.
