Question:
A country charges income tax as follows based on one's gross salary. No tax is charged on the
first 20% of salary. The remaining 80% is called taxable income. Tax is paid as follows:
10% on the first $15,000 of taxable income;
20% on the next $20,000 of taxable income;
25% on all taxable income in excess of $35,000;
Write a program to read a value for a person's salary and print the amount of tax to be paid in
dollars.

Exercise 6:
Write a program that reads from the user three pieces of information: The current population of a country, the annual birth
rate of the country, and its annual death rate. The program should then calculate the expected population for the following
year and display the results as shown in Figure 6.
Please note that population for the following year is calculated as sum of the current population, and the number of births
by the end of the year minus the number of deaths by the end of the same year.
Name your program Lab3_Id_ex6.py, where Id is your university Id. Include the design of your solution as comments
at the beginning of your program. Test your solution with different input data.
Please enter the current population of the country: 1800000
Please enter the birth rate: 0.017
Please enter the death rate: 0.005

- 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; }arrow_forward(Modify) a.
