- Python Code Needed Problem: A company wants a program that will calculate the weekly paycheck for an employee based on how many hours they worked. For this company, an employee earns $20 an hour for the first 40 hours that they work. The employee earns overtime, $30 an hour, for each hour they work above 40 hours. Example: If an employee works 60 hours in a week, they would earn $20/hr for the first 40 hours. Then they would earn $30/hr for the 20 hours they worked overtime. Therefore, they earned: ($20/hr * 40hrs) + ($30/hr * 20 hrs) = $800 + $600 = $1400 total. For this assignment, you must create pseudocode and a flowchart to design a program that will calculate an employee’s weekly paycheck. Write pseudocode to design a programming solution by outlining a series of steps and using appropriate indentation and keywords. As you write your pseudocode, be sure to consider the following: What input does the computer need? What steps does the program need to follow to process the input?…arrow_forwardFundamentals of Programming in C Language Write the value of each of the following expressions, using the following data declarations: double m = 17.5; int y = 9; 1.

Night (8.00 P.M. to 7.00 A.M.) and weekend (Saturday to Sunday) minutes are free, but additional weekday minutes cost RMO.20 each. There are Service taxes (SST) of 6% on all charges. Write a program that prompts the user to enter the number of weekday minutes, night minutes, and weekend minutes used, and calculates the monthly bill and average cost of a minute before taxes. The program should display with labels all the input data, the pre-tax (amount before tax) bill and average minute cost, the SST cost and finally the total bill. Store all amount values as whole cents (rounding the taxes and average minute cost ie: RMS.54 and 253 minutes).arrow_forward
