Today we have a discussion starter question for you, inspired by a trip to the shops.
My shopping cost £40.95 today. What is the smallest number of coins required to make this amount?
If I paid with two £20s and a £10 note, what is the most efficient change?
Why would someone pay £41.05, as opposed to £41?
I purchased 17 items, do you have enough information to calculate the mean?
The most expensive item was £10, the cheapest was 45p. What does this allow you to calculate?
Two luxury items cost £9 in total. If I hadn’t bought these, what would the mean have been? Does this effect the range?
When I paid I was given this voucher:
What would the shopping have cost somewhere else?
What would the mean cost per item be after this discount?
What percentage discount is this?
You could also use this as a discussion starter about the number skills you use when you go shopping.
