4. 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; }
(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
(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.
The cost of renting a room at a hotel is, say $100.00 per night. For special occasions, such as a wedding or conference, the hotel offers a special discount as follows: If the number of rooms booked at least 10, the discount is 10%; at least 20, the discount is 20%; and at least 30, the discount is 30%. Also if rooms are booked for at least three days, then there is an additional 5% discount. Write a program that prompts the user to enter the cost of renting one room, the number of rooms booked, the number of days the rooms are booked, and the sales tax (as a percent). The program outputs the cost of renting one room, the discount on each room as a percent, the number of rooms booked, the number of days the rooms are booked, the total cost of the rooms, the sales tax, and the total billing amount. Your program must use appropriate named constants to store special values such as various discounts.
C++ Programming Exercise: 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: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.
1. Federal law requires that hourly employees be paid “time-and-a-half” for work in excess of 40 hours in a week.For example, if a person’s hourly wage is $12 and he or she works 60 hours in a week, the person’s gross pay shouldbe (40 *12) + (1.5 *12 * (60-40)) = $840.Write a program that requests the floating number of hours a person works in a given week and the person’s hourlywage as input, and then displays the person’s gross pay. Save it as overtimePay.py
An 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.
The New Telephone Company has the following rate structure for long-distance calls: The regular rate for a call is P8 per minute. Any call started after 6:00P.M. (1800 hours) but before 8:00 A.M (0800 hours) is discounted 50%. Any call longer than 60 minutes receives a 15% discount. All calls are subject to 4% federal tax on the cost after any discounts. Write a program that takes the start time for a call based on a 24-hour clock and the length of the call in minutes. The gross cost (before any discounts or tax) should be displayed followed by the net cost (after discounts are deducted and tax is added).
. The progressive income tax rate is mandated as follows: Taxable Income Rate (%) First $20,000 0 Next $20,000 10 Next $20,000 20 The remaining 30 For example, suppose that the taxable income is $85000, the income tax payable is $20000*0% + $20000*10% + $20000*20% + $25000*30%. Write a program called IncomeTaxCalculator that reads the taxable income (in int). The program shall calculate the income tax payable (in double); and print the result rounded to 2 decimal places. For examples, Enter the taxable income: $41234 The income tax payable is: $2246.80 Enter the taxable income: $67891 The income tax payable is: $8367.30 Enter the taxable income: $85432 The income tax payable is: $13629.60 Enter the taxable income: $12345 The income tax payable is: $0.00

Suppose you have a certain amount of money in a savings account that earns compound monthly interest, and you want to calculate the amount that you will have after a specific number of months. The formula is as follows: f = p * (1 + i)^t • f is the future value of the account after the specified time period. • p is the present value of the account (the account's current balance). • i is the monthly interest rate. • t is the number of months. Write a program that takes the account's present value (current balance), monthly interest rate, and the number of months that the money will be left in the account as three inputs from the user. 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 print the account's future value. Look carefully at the following sample run of the program. In particular, notice the wording of the messages and the placement of…
