Question

The tax calculator program of the case study outputs a floating-point number that might show more than two digits of precision.

Answer 1

Answer:

TAX_RATE = 0.20

STANDART_DEDUCTION = 10000.0

DEPENDENT_DEDUCTION = 3000.0

gross_income = float(input("Enter the gross income: "))

number_of_dependents = int(input("Enter the number of dependents: "))

income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents)

tax = income * TAX_RATE

print ("The income tax is $" + str(round(tax, 2)))

Explanation:

Define the constants

Ask user to enter the gross income and number of dependents

Calculate the income using formula (income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents))

Calculate the tax

Print the tax

round(number, number of digits) -> This is the general usage of the round function in Python.

Since we need two digits of precision, we need to modify the program as str(round(incomeTax, 2)).
