Rate of Inflation
The annual rate of inflation is the rate at which money loses its value. For example, if the annual rate of inflation is 3.0 percent, then in one year it will cost $1,030 to buy the goods that could have been purchased for $1,000 today. Put another way, a year from now $1,000 will only buy 1/1.03 * $1,000, or $970.87, worth of goods. Two years from now, $1,000 will only buy only 1/1.03 of $970.87, or $942.59 worth of goods. Write a

- The profit from the sale of a stock can be calculated as follows: Profit ((NS SP) SC) ((NS PP) PC)where NS is the number of shares, SP is the sale price per share, SC is the sale commission paid, PP is the purchase price per share, and PC is the purchase commission paid. If the calculation yields a positive value, then the sale of the stock resulted in a profit. If the calculation yields a negative number, then the sale resulted in a loss.Write a function that accepts as arguments the number of shares, the purchase price per share, the purchase commission paid, the sale price per share, and the sale commission paid. The function should return the profit (or loss) from the sale of stock.Demonstrate the function in a program that asks the user to enter the necessary data and displays the amount of the profit or loss.arrow_forwardLeap years have 366 days (29 Any year that is divisible by 4 but not by 100 is a leap year. If a year is divisible by 400 then it is also a leap year. So in short any year that is divisible by 4 is a leap year, unless it is divisible by 100, in which case it must also be divisible by 400 for it to be a leap year. Example: 1996 and 2000 were leap years, but 1900 was not. days in February).arrow_forwardOne way to determine how healthy a person is by measuring the body fat of the person.

- A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: The year must be divisible by 4 If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is 1712, the output is: 1712 is a leap year. Ex: If the input is 1913, the output is: 1913 is not a leap year. 1 2 3 4 5 6 7 8 9 10 11 Put("{} is a leap year.".format(i_year)) print("{} is not a leap year.".format(i_year)) inputYear = Get next input What would be the code?arrow_forwardInterest on a credit card’s unpaid balance is calculated using the averagedaily balance. Suppose that netBalance is the balance shown in the bill, payment is the payment made, d1 is the number of days in the billing cycle, and d2 is the number of days payment is made before billing cycle. Then, the average daily balance is:averageDailyBalance = (netBalance * d1 – payment * d2) / d1If the interest rate per month is, say, 0.0152, then the interest on the unpaid balance is:interest = averageDailyBalance * 0.0152Write a program that accepts as input netBalance, payment, d1, d2, and interest rate per month.

- Summary When you borrow money to buy a house, a car, or for some other purposes, then you typically repay it by making periodic payments. Suppose that the loan amount is L, r is the interest rate per year, m is the number of payments in a year, and the loan is for t years. Suppose that i = (r / m) and r is in decimal. Then the periodic payment is (first image which R=....): You can also calculate the unpaid loan balance after making certain payments. For example, the unpaid balance after making k payments is (second image which L'=....) : where R is the periodic payment. (Note that if the payments are monthly, then m = 12.) Instructions Write a program that prompts the user to input the values of L, r, m, t, and k. The program then outputs the appropriate values. Your program must contain at least two functions, with appropriate parameters, to calculate the periodic payments and the unpaid balance after certain payments.

As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consume in a day. Then, she calculates the number of calories that result from the fat using the following formula: Calories from fat = Fat grams × 9Next, she calculates the number of calories that result from the carbohydrates using the following formula: Calories from carbs = Carbs grams × 4Create an application that will make these calculations. In the application, you should have the following methods:• FatCalories–This method should accept a number of fat grams as an argument and return the number of calories from that amount of fat.• CarbCalories–This method should accept a number of carbohydrate grams as an argument and return the number of calories from that amount of carbohydrates.arrow_forward
- Coin Exchange: Write a program that will determine how many coins of each denomination (50kr, 25kr, 10kr, Skr, and 1kr) are required to make up a given amount of change. For example, to make 57kr we could use 1 x 50kr, 1 x 5kr, and 2 x 1kr., It should be obvious that many combinations of coins are possible. For example, in the example above, we could make up 57kr with: (57 x 1kr) or (2 x 25kr and 7 x 1kr). However, your program must use the smallest number of coins (10 points). Example program output: Enter amount: 40 40 Kr = 1 x 25Kr 1х 10Кr 1 x 5Krarrow_forwardInterest on a credit card’s unpaid balance is calculated using the average daily balance. Suppose that netBalance is the balance shown in the bill, payment is the payment made, d1 is the number of days in the billing cycle, and d2 is the number of days payment is made before billing cycle. Then, the average daily balance is: averageDailyBalance = (netBalance * d1 - payment * d2) / d1. The interest on the unpaid balance is: interest = averageDailyBalance * interestRate where interestRate is the interest rate per month. Write a program that accepts as input netBalance, payment, d1, d2, and interestRate. The program outputs the interest. Format your output to two decimal places. Analyze and design this program.

These equations are usually written in the following form:ax2 + bx + c = 0The Quadratic Formula x = ( -b ± √( b^2 - 4ac ) ) / ( 2a ) Where a, b, and c are constants with a ≠ 0. (If a = 0, the equation is a linear equation.)The discriminant is the part of the formula in the square root. If the value of the discriminant is zero then the equation has a single real root. If the value of thediscriminant is positive then the equation has two real roots. If the value of thediscriminant is negative, then the equation has two complex roots.Write a program that finds the roots of the quadratic equation using the Quadratic Formula. Write a function named discriminant in the file, Disc.py, to calculate and return the discriminant of the formula. Let the main function call the discriminant function and then calculate the solution(s) of the equation. Do not calculate the solutions in the discriminant…arrow_forward
