- When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)arrow_forwardC Language Given three floating-point numbers x, y, and z, output x to the power of z, x to the power of (y to the power of 2), the absolute value of y, and the square root of (xy to the power of z).

- Construct C++ program to solve a given problem using appropriate programming techniques. Write a program that will calculate and print bills for the city power company. The rates vary depending on whether the use us residential, commercial, or industrial. A code of R means residential use, a code of C means commercial use, and a code of I means industrial use. Any other code should be treated as an error. The rates are computed as follows: R: $6.00 plus $0.052 per kwh used. C: $60.00 for the first 1000 kwh and $0.045 for each additional kwh. I: Rate varies depending on time of usage Peak hours: $76.00 for first 1000kwh and %0.065 for each additional kwh. Off-peak hours: $40.00 for first 1000 kwh and $0.028 for each additional kwh. Your program should prompt the user to enter an integer account number, the use code (type char), and the necessary consumption figures in whole numbers of kilowatt-hours. Your program should display the amount due from the user.arrow_forwardWrite PHP statements to accomplish each of the following tasks: a) Declare a variable aCo and bCo and assign 32 to both variables. b) Increment a variable bCo after assigning 32 to the variable. c) Declare a variable average to hold the average value of variables aCo and bCo;arrow_forwardCHALLENGE ACTIVITY 4.4.5: Multi-branch if-else statements: Print century.
