item2 = 0.0
item3 = 0.0
item4 = 0.0
item5 = 0.0
subtotal = 0.0
tax = 0.0
total = 0.0
# Constant for the sales tax rate.
TAX_RATE = 0.07
# Get the price of each item.
item1 = float(input(“Enter the price of item #1: “))

# Calculate the subtotal.
subtotal = item1 + item2 + item3 + item4 + item5
# Calculate the sales tax.
tax = subtotal * TAX_RATE
# Calculate the total.
total = subtotal + tax
# Print the values.
