Answer:
The function is correct, I just don't see a question.
Step-by-step explanation: 6 21 6 10
C(n) = 12n + 65
I will make up a question. How much will it cost 4 people each to rent the cabin?
C(n) = (12n + 65) / n n = 4
= (12 × 4 + 65) / 4
= (48 + 65) / 4
= 113 / 4
= $28.25
If your question is differnt just substitute the number of people into the question and solve for C(n)
Answer:47.25
Step-by-step explanation: it is 10.5 x the 4.5
let h= history books
science books = s
h=2s there are 2 times as many history as science so to get them equal we double the science
h+s=81 there are 81 total history and science books
2s+s=81 substitute 2s for h in the above equation
3s = 81 combine like terms
s = 27
There are 27 science books
h=2s
h=2(27)
h=54
there are 54 history books
