Ronan · 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))

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
