- The following is an example problem: A customer in a store is purchasing five items. Write a python program that asks for the price of each item, them displays the subtotal of the sale, the amount of sales tax, and the total. Assume the sales tax is 7 percent.arrow_forwardPYTHON write a program that assigns the principal amount of P10000 to variable P, assign to n the value 12, and assign to r the interest rate of 8%. then have the program prompt the user for the number of years t that the money will be compounded for. calculate and print the final amount after t years. use the formula below.arrow_forwardI'm stuck on this problem, and here's what I'm stumped on: Meadowdale Dairy Farm sells organic brown eggs to consumers in the surrounding area. For a dozen eggs, it charges $3.25, and for individual eggs that are not part of a dozen, it charges 45 cents each egg. Using the following phrasing, write a program that prompts a user to enter the number of eggs in the order and then displays the amount owed along with a detailed explanation of why the amount is due: You placed an order for 27 eggs. There are 2 dozen eggs at $3.25 per dozen and 3 loose eggs at 45 cents each, which adds up to a total of $7.85.arrow_forward
- Write a Python program that prompts the user to enter a numeric temperature value that may be a float. A second prompt should then ask the user to indicate whether the user wants the entered temperature value converted to degrees Celsius or degrees Fahrenheit by entering either an 'F' or a 'C' for a second prompt. For example, if the user enters 212 at the first prompt and the character C for the second prompt you are to convert 212 degrees F to the Celsius equivalent (which would be 100.0). Converted temperatures should be rounded to 1 decimal place. If the user enters 26 at the first prompt and the character F at the second one, then your programs should convert 26 degrees C to the Fahrenheit equivalent (which is 78.8 deg F) Your conversion formulas are: degF = 1.8 * degC + 32 //convert Celsius to Fahrenheit degC = (degF - 32) / 1.8 //convert Fahrenheit to Celsius Have your converted values be floats rounded to 1 decimal place. The F or C entry should be case-insensitive.…arrow_forwardplease use pythonarrow_forwardWrite a python program that asks the user to enter the monthly costs for the following expenses incurred from operating his or her automobile: loan payment, insurance, gas, oil, tires, and maintenance.
