Analyze the problem• Your job – what are the inputs and outputs3. Design the algorithm to solve the problem• Your job – write it down and turn it in!4. Implement the algorithm• Your job5. Test and verify the completed program• Your job – this is the most time consuming part• Go back to step 4 if your program fails the tests6. Maintain and update the program• Always assume you will reuse your code at some pointAlgorithms• Step-by-step procedure for solving aproblem• Be as specific as possible – include allsteps• Example – doing your laundryCalculate Tax on an Item• Problem• Analysis• Algorithm design• Implementation• Testing• Maintenance#A program to calculate tax and total cost for an item.#determine rate of taxation#ask user for the cost of the item#calculate the tax#calculate total cost#display the results2#Name: Sami Rollins#A program to calculate tax and total cost for an item.#determine rate of taxationTAX_RATE = .0825#ask user for the cost of the itemcost = input("Enter item cost: ")#calculate the taxtax = cost*TAX_RATE#calculate total costtotal = cost+tax#display the resultsprint "Cost: ", costprint "Tax : ", taxprint "Total: ", total#Name: Sami Rollins#A program to calculate tax and total cost for an item.• Indicates what the program does• Comments– # to the end of the lineHeading#determine rate of taxationTAX_RATE = .0825• Sets the value of the variable TAX_RATEto be .0825Variables#ask user for the cost of the itemcost = input("Enter item cost: ")• Prompt the user for the cost of the itemand store the response in the variable costInput#calculate the taxtax = cost*TAX_RATE• Multiply the cost times the tax rate andstore the result in the variable taxCalculation#calculate total costtotal = cost+tax• Add the cost and the tax and store theresult in the variable totalCalculation3#display the resultsprint "Cost: ", costprint "Tax : ", taxprint "Total: ", total• Display the results for the userOutputExercises1. Write the algorithm for a program thattakes as input the number of miles a carhas traveled and the number of gallonsof gas the car has consumed andcalculates the number of miles the carcan travel on one gallon of gasExercises2. Write the program for the algorithm youjust generated using the tax program asa
