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

Please help me I don't understand any of this.

Just substitute those values for n to calculate C.

No worries! I'll be happy to help you understand this. Let's break it down step by step.

First, let's understand the given function rule: C = 10n + 26. This means that the cost of the concert (C) is calculated by multiplying the number of people attending (n) by 10, and then adding 26 to the result.

To create a table of input/output pairs, we'll substitute the given numbers of people attending (27, 39, and 43) into the function and calculate the corresponding cost.

For 27 people:
C = 10n + 26
C = 10(27) + 26
C = 270 + 26
C = 296

So, when 27 people attend the concert, the cost will be $296.

For 39 people:
C = 10n + 26
C = 10(39) + 26
C = 390 + 26
C = 416

So, when 39 people attend the concert, the cost will be $416.

For 43 people:
C = 10n + 26
C = 10(43) + 26
C = 430 + 26
C = 456

So, when 43 people attend the concert, the cost will be $456.

To summarize, the table of input/output pairs for the given function rule C = 10n + 26 is as follows:

Number of People (n) | Cost (C)
--------------------------------------
27 | $296
39 | $416
43 | $456

I hope this clarifies everything for you!
