# Create a program where you manage what a cash register does.
# You will receive three receipt inputs each with an amount (int) and tax percentage (int) 
# calculate how much from the amount paid is tax.

# A - 18% Tax
# B - 10% Tax
# C - 7% Tax
# Output what the total amount of tax paid is

# Input
# 10000 A
# 7500 B
# 18000 C
# 11500 B

# Output
# Total VAT paid: 4960
