- An employee’s total weekly pay equals the hourly wage multiplied by the total number of regular hours plus any overtime pa y. Overtime pay equals the total overtime hours multiplied by 1.5 times the hourly wage. Write a program that takes as inputs the hourly wage, total regular hours, and total overtime hours and displays an employee’s total weekly pay.arrow_forwardWRITE A PROGRAM TO CALCULATRE THE AREA OF A RECTANGLE OF LENGTH =5 CM AND BREADTH=8CM. CALCULATE THE PRICE OF AN ITEM COSTING 100 GHANA CEDIS AFTER A DISCOUNT OF 10% IS APPLIED TO IT. WRITE A PROGRAM TO CALCULATE THE SIMPLE INTEREST ON A LOAN AMONUT OF 50000 GHANA CEDIS AT AN INTEREST RATE OF 30% FOR A NUMBER OF YEARS WHICH WILL BE SPECIFIED BY THE USER. WRITE A PROGRAM TO CALCULAT THE AGE OF THE USER AFTER THE USER ENTERS HIS OR HER YEAR OF BIRTH.arrow_forwardTwo cars A and B leave an intersection at the same time. Car A travels west at an average speed of x miles per hour and car B travels south at an average speed of y miles per hour. Write a program that prompts the user to enter the average speed of both the cars and the elapsed time (in hours and minutes) and outputs the (shortest) distance between the cars.arrow_forward
- A contractor orders, say, 30 cubic yards of premixed concrete to construct a patio that is to be, say, four inches thick. The length of the patio is to be, say, twice the width. Write a program that prompts the user to specify the amount of premixed concrete (in cubic yards) ordered, the thickness of the patio (in inches), and the ratio of length and width. The program then outputs the length and width of the patio (in feet). (1 cubic yard 5 27 cubic feet.) (To find the square root of a decimal number, include the header file cmath using the statement #include <cmath>, in your program. The function sqrt, included in this header file, determines the square root of a decimal number. For example, sqrt(16.0) = 4.0.)arrow_forwardAn oil slick occurs when an underwater refinery pipe ruptures, pumping oil into the water. The spilled oil sits on top of the water and causes a natural disaster. For simplicity, suppose that the oil sits on top of the water in the form of a circle. Write a program that prompts the user to enter the rate at which the ruptured pipe pumps oil (in gallons) per minute, the thickness of the oil on top of the water, and the number of days for which the area is covered by the spilled oil. The program outputs the spilled area (in kilometer) and the volume of oil (in gallons) on top of the water after each day.arrow_forwardFor each used car a salesperson sells, the commission is paid as follows: $20 plus 30% of the selling price in excess of the cost of the car. Typically, the minimum selling price of the car is the cost of the car plus $200 and the maximum selling price is the cost of the car and $2,000. Write a program that prompts the user to enter the salesperson’s fixed commission, the percentage of the commission, the purchasing cost of the car, the minimum and maximum amount to be added to the purchasing cost to determine the minimum and maximum selling price, and outputs minimum and maximum selling price of the car and the salesperson’s commission range.arrow_forward
- Paula and Danny want to plant evergreen trees along the back side of their yard. They do not want to have an excessive number of trees. Write a program that prompts the user to input the following:a. The length of the yard.b. The radius of a fully grown tree.c. The required space between fully grown trees.The program outputs the number of trees that can be planted in the yard and the total space that will be occupied by the fully grown trees.arrow_forwarddraw a flowchart for a program that will compute and output the sales tax due with a tax rate of 7% and total purchase price of 4 items.list the neccesary varibles for this program.perform a desk check with the following values 2.99,3.99,7.50 and 2.75.arrow_forwardWrite a program to calculate velocity of a car when distance and time are given by the user.arrow_forward
- (Modify) a. Modify the program you wrote for Exercise 7 to provide the mass of a person as an output, given his or her weight as an input to the program. Use your program to determine the mass of a person who weighs 140 lbf on Earth. b. Modify the program written for Exercise 7a to also output the person’s weight on Mars and the moon. The pull of gravity on Mars is 12.54ft/sec2=3.728m/s2,andonthemoonis5.33ft/sec2=1.625m/s2.arrow_forward4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward26. A room has one door, two windows, and a built-in bookshelf and it needs to be painted. Suppose that one gallon of paint can paint 120 square feet. Write a program that prompts the user to input the lengths and widths of the door, each window, the bookshelf; and the length, width, and height of the room (in feet). The program outputs the amount of paint needed to paint the walls of the room.arrow_forward
