If you use 60 minutes or less in a month you pay $17.99 in usage charges. If you use between 60 and 120 minutes you pay the $17.99 plus $0.25 per minute for each minute over 60 in usage charges. If you use more than 120 minutes you pay $29.99 plus $0.15 per minute for each minute over 120 in usage charges. In addition, there are a $7 processing charges per month. Then there is an 8% sales tax on all charges.
Create a worksheet that allows you to enter the minutes used and then shows you the usage charge, the processing charge, the tax, the total charge, and the average total cost per minute. Try your worksheet with inputs of 10 minutes, 100 minutes, and 5000 minutes.

Your friend kayla is starting her own business and asks you whether she should set it up as a p2p network or as a client-server network. list three questions you might ask to kayla decide which network to use and how her answers to those questions would affect your recommendation.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
