Answer: Our Cost function is discontinuous at every integer after x>10.
Step-by-step explanation:
Since we have given that
For the first 10 minutes , the service charges = $0.30
Let the number of additional minute be 't'.
Amount charge for each additional minute = $0.05
Using the greatest integer function:
So, Cost C of a call in terms of time 't' minutes would be
As we know that Greatest integer is discontinuous at every integer.
So, our Cost function is discontinuous at every integer after x>10.

Answer:
A score of 95 she must obtain on the fifth exam to have an average of 90 or better for the five exams
Step-by-step explanation:
average = sum of all terms / number of terms
average = 94 + 83 + 92 + 86 + x / 5
90 = 355 + x / 5
multiply both sides by 5,
90 * 5 = 355 + x / 5 * 5
450 = 355 + x
subtract 355 from both sides to get x alone
450 - 355 = 355 + x - 355
95 = x
