Part 1 - Exercise 3 Solution

-- Problem: Given a number of party guests, pizzas and slices per
-- pizza, calculate how many slices each person should get so that
-- everyone has the same number of slices. Also calculate the number
-- of leftover slices.
-- Solution: First, calculate the total number of slices available.
-- Input
guests = 5
pizzas = 2
slices_per_pizza = 8
print("There are " .. guests .. " guests.")
print("We ordered " .. pizzas .. " pizzas.")
print("Each pizza has " .. slices_per_pizza .. " slices.")
-- Calculation
slices_total = pizzas * slices_per_pizza
slices_per_guest = math.floor(slices_total / guests)
leftover_slices = slices_total - slices_per_guest * guests
-- Output
print("Each person gets " .. slices_per_guest .. " slices of pizza.")
print("There will be " .. leftover_slices .. " leftover slices.")
