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!
