We calculated the cost of Christmas, based on the song, The twelve days of Christmas. We got a list of prices from the internet, a partridge in a pear tree costs $93, but if you want to buy one online the cost, including delivery, would be $147.50.
The calculation was set out in a table, working out the cost of sending 12 partridge in a pear tree, then 11 x 2 turtle doves, 10 x 3 french hens and so on...
And the grand total was $66, 301.92
The calculations are linked to Pascal's triangle. We looked at this, but it was very tricky to understand, but we could see the pattern when it was highlighted. They was also some link to Fibonacci.
