(Interest Calculator) The simple interest on a loan is calculated by the formula
Interest = principal * rate * days / 365;
The preceding formula assumes that rate is the annual interest rate, and therefore includes the division by 365 (days). Develop a

(Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the following 2 X 2 system of linear equation: ax + by = e cx + dy = f ● x = ed - bf bc ad y = af - ec ad bc - Write a program that prompts the user to enter a, b, c, d, e, and f and display the result. If ad- bc is 0, report that The equation has no solution. Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter x is -2.0 and y is 3.0 Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter The equation has no solutionarrow_forwardNeed help with this C++ code. Thank you.arrow_forwardChange Return Program: (Write a python program for the following) The user enters a cost and then the amount of money given. The program will figure out the change and the number of twenty-dollar bills, ten-dollar bills, five-dollar bills, single-dollar bills, quarters, dimes, nickels, pennies needed for the change. You must have the maximum amount of higher denominations possible before allowing for lower denominations. For example, If your change is $18.88, You must have One Ten-dollar bill, One Five-dollar bill, Three singles, Three quarters, One dime and three pennies. There should be no nickels; No three Five-dollar bills etc.arrow_forward
- Please use Visual Studios coding in Python. (Use Python 3 Version)arrow_forward(Python) Please write a program that creates steps. You are expected to take in a single positive integer which will be used as the number of steps in your staircase. The program only accepts integers greater than 0 and less than 500. If 0 is entered a message stating "Your staircase has no steps." and if the user enters a value greater than or equal to 500, a message stating "I can't build a staircase that tall." For all other values not within the valid range or not integers an "Invalid staircase size provided." will be displayed to the user. The program will always run only once for each user input. One thing to note, the messages should be the return string from your printSteps() function and printed from the calling function. Additional Requirements: The very first step in the staircase will be left-aligned and for each subsequent level, the step will move above and to the right of the prior step. There are no spaces after the right of any of the steps. The bottom-most row ends…arrow_forward( MindTap - Cenage )Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high. Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess). If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number. Suppose diff is not 0. Then the program outputs the message as follows: If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num). If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num). If diff is greater than or equal to 15 and less than 30, the…arrow_forward
- need help with these. a flowchart and a code written in c languagearrow_forwardLanguage: C++ (Apartment problem) A real estate office handles , say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: The total number of units. The rent to occupy all the units. The increase in rent that results in a vacant unit. Amount to maintain rented unit. The program then outputs the number of units to be rented to maximize the profit. Note: Please include the pseudocodearrow_forwardPlease review the image below. Produce the program in C++.

- (Algebra: solve 2 x 2 linear equations) You can use Cramer's rule to solve the following 2 x 2 system of linear equation: ax + by = e ed – bf af- ec ad - bc cx + dy = f ad – bc y = Write a program that prompts the user to enter a and f and display the result. If ad - bc is 0 b, c, d , e, , report that The equation has no solution.arrow_forward(Converting a given date to the day number in the year) Write a program that prints the day number of the year, given the date is in the form month day year. For example, if the input is 1 1 05, the day number is 1; if the input is 12 25 05, the day number is 359. The program should check for a leap year. A year is a leap year if it is divisible by 4 but not divisible by 100. For example, 1992 and 2008 are divisible by 4, but not by 100. A year that is divisible by 100 is a leap year if it is also divisible by 400. For example, 1600 and 2000 are divisible by 400. However, 1800 is not a leap year because 1800 is not divisible by 400. Directions: Call 3 functions from your main. One to input data (pass parameters in a list) One to determine the result (use a value returning function to determine and return the result) One to display both the date and the result You can use two Python dictionaries to represent the number of days in each month for a regular and a leap year.

Two other marketing terms are percentage markup=makeup/(purchase price) and profit margin= makeup/(selling price) where the quotients are expressed as percentages. Write a program that computes the markup, percentage markup, and profit margin of an item. Note: The output format of your program should be exactly the same as given below One possible outcome: Enter purchase price: 215 Enter selling price: 645 Markup: $430.0 Percentage markup: 200.0% Profit margin: 66.67%arrow_forward
