Write a program that calculates the electricity bill. The rates of electricity per unit are as follows: If the units consumed are <=300, then the cost is Rs. 12 per unit. If the units consumed are >300 and <=500, then the cost is Rs. 17 per unit. If the units consumed exceed 500 then the cost per unit is Rs. 22 A line rent of Rs. 1500 is also added to the total bill and surcharges of 5% extra if the bill exceeds Rs. 15000. Calculate the total bill with all the conditions given above.

Suppose you have a certain amount of money in a savings account that earns compoundmonthly interest, and you want to calculate the amount that you will have after a specificnumber of months. The formula is as follows: F=P×(1+i)tF=P×(1+i)t The terms in the formula are:     • F is the future value of the account after the specified time period.• P is the present value of the account.• i is the monthly interest rate.• t is the number of months.• F is the future value of the account after the specified time period.• P is the present value of the account.• i is the monthly interest rate.• t is the number of months. $$ Write a program that prompts the user to enter the account’s present value, monthly interest rate, and the number of months that the money will be left in the account. The program should pass these values to a function that returns the future value of the account, after the specified number of months. The program should display the account’s future value.

а. Write a program that calculates and prints the fare for an airline. There are two plans: Plan Ticket fare Baggage Weight Fare Tax Economy 1200 $ 25 18% or 10% Business 3000 $ 35 20% or 12% Extra weight is charged by 20$/Kg for Economy, and 15$ for Business. A fare tax is added to the ticket fare: 18% for Economy and 20% for Business if the ticket type is "roundtrip". The fare is 10% for Economy and 12% for Business if the ticket type is "one-way". The tax percentage is applied on the original ticket fare. i. Ask the user to enter the Customer ID. A valid Customer ID must contain 5 digits. If the user inputs an invalid Customer ID the user must re-enter the account. Ask the user to enter the plan code (The user will enter e or E for Economy and b or B for Business). Any invalid input must be corrected by asking the user to re-enter. ii. iii. Ask the user to enter the weight. You may assume that the user will not enter a negative number. iv.

You are working for a lumber company, and your employer would like a program that calculatesthe cost of lumber for an order. The company sells pine, fir, cedar, maple, and oak lumber.Lumber is priced by board feet. One board foot equals one square foot that is one inch thick. Theprice per board foot is given in the following table: (image 1) The lumber is sold in different dimensions (specified in inches of width and height, and feet oflength) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which whendivided by 12 = 5.333 board feet). An entry from the user will be in the form of a letter and fourinteger numbers. The integers are the number of pieces, width, height, and length. The letter willbe one of P, F, C, M, O (corresponding to the five kinds of wood) or T, meaning total. When theletter is T, there are no integers following it on the line. The program…
