Answer:
The cost of making 60 calls a month is $20.
Step-by-step explanation:
There was a small typing mistake there. If the fixed charge is $14, the cost of n calls is given by the following equation:

Find the cost of making 60 calls a month.
This is C(60), that is, C when n = 60. So


The cost of making 60 calls a month is $20.
This is the concept of algebra. Given that Holly has 30 pencils, the total number of pencils that Holly remained with after she gave her friends 6 pencils are:
Total=30-6=24 pencils
The fraction of pencils that need to be sharpened is 3/8
The number of pencils represented by this fraction will be:
(fraction of un-sharpened pencils)×(total number of remaining pencils)
3/8×24
=9 pencils
therefore we conclude that 9 pencils are not sharpened.
Answer: (5,3) y= 6(5)-27 = 3 y=4(5)-17= 3
