From The Editor’s Laptop
I know by the time you read this, Christmas will be over, but I’ve been listening to Christmas carols all day and having fun thinking about some of the math. I haven’t solved any of these problems yet, so feel free to pass on the answers or to think of more fun problems. The most common one I’ve run into is, How much do the 12 days of Christmas cost if you only give each gift once, or if you repeat the first gift on day two, the first and second on day three and so on?
But today I am wondering, if we consider just the cost of feed, is it more efficient for Santa to feed his reindeer for an entire year to use for one day or to buy a new set every year?
Or if Santa only travels to cities with a population of over 500,000 (or pick any number), how many kilometres does he have to travel? Connected to the previous problem, if Santa fed the animals all year, how many kilometres are travelled per kilogram of food eaten?
Hope you enjoy!
