Answer 1

The following c‎odes have been written using Python.

while True:

   nc = int(input("Enter the number of calls: "))

   print()

   cc = 0

   if nc <= 50:

       cc = nc*0

   elif nc <= 100:

       cc = nc*0.50

   elif nc <= 200:

       cc = nc*0.80

   elif nc > 200:

       cc = nc*1.20

   print(cc, "is the cost.")

   print("A rent of 120 and a tax of 15% will be charged.")

   print()

   cc = cc + 120

   cc = ((cc*15)/100) + cc

   print(cc, "is your total cost [cost + rent + tax].")

   print()

   c = input("Next customer? [Y/N]: ")

   print()

   if c in "Yy":

       continue

   else:

       break
