# Quiz: Calculate
# In this quiz you're going to do some calculations for a tiler. Two parts of a floor need tiling. 
# One part is 9 tiles wide by 7 tiles long, the other is 5 tiles wide by 7 tiles long. Tiles come 
# in packages of 6.

#1. How many tiles are needed?
#2. You buy 17 packages of tiles containing 6 tiles each. How many tiles will be left over?




# Fill this in with an expression that calculates how many tiles are needed.
# This question is tricky, if you mean THE NUMBER OF TILES, then this is the solution
print((9*7) + (5*7))

# If you mean THE NUMBER OF PACKAGES, then this is the solution
print(((9*7) + (5*7)) / 6)

# Fill this in with an expression that calculates how many tiles will be left over.
print((17*6) - ((9*7) + (5*7)))
