The Panini World Cup Sticker Challenge.
Thanks to Abi Stokes (@Abicass1) for giving me this idea.
Very topical with the England squad being announced today (well done to Southampton's Adam Lallana, Rickie Lamber and Luke Shaw)
We love to collect football stickers and fill our albums, but how much would it cost to fill your book?
In this year’s sticker book South Korean striker Lee KeunHo is at number 639. Stickers come in packs of five, so:
QUESTION 1: How many packets would you need to get 639 stickers?
QUESTION 2: If each pack costs 50, how much would it cost to buy the number of packs needed?
Of course when buying packets you will get some of the same stickers, with this in mind on average you would need to buy 4120 stickers.
QUESTION 3: How many packs of 5 would you need to buy?
QUESTION 4: How much would it cost?
