Question

Create a simple self-checkout system. Prompt for the prices and quantities of three items. Calculate the subtotal of the items. Then calculate the tax using a tax rate of 6.5%. Print out the line items with the quantity and total, and then print out the subtotal, tax amount, and total.

Answer 1

subtotal = 0

total = 0

tax_rate = 6.5

for i in range(1,4):

price = float(input("Enter the price for item " + str(i) + ": "))

quantity = int(input("Enter the quantity for item " + str(i) + ": "))

subtotal += (price * quantity)

tax = subtotal * tax_rate/100

total = tax + subtotal

print("Subtotal: " + str(subtotal) + ", Tax: " + str(tax) + ", Total: " + str(total))

Step-by-step explanation:

- Initialize the variables

- Create for loop that iterates 3 times

- Ask the user for the price and quantity of each item

- Calculate the subtotal with given inputs

- When the loop is done, calculate the tax and total

- Print the subtotal, tax, and total
