Gloria Hunniford: Within our advice shop, the literacy and numeracy team from BBC Skillswise has put together a series of practical scenarios to test your consumer skills.

Jo: See things like 50% off and 10% off and half price and you don’t really know what that means really. So it’s about going in and finding out what the actual price of the dress or the hat or the bag is, helping you find the best deal.

Woman: The normal price is £30 so 50% of that would make £15. 10% of £20 is £2 so that would be £18. And then 30% of a handbag at £12.99, so one 10% is £1.29, so you multiply £1.29 by three. I took that off the ticket price of £12.99, and then you add them altogether which gets you a total of £42.12.

Jo: So that’s the total price for everything on the mannequin.

Gloria Hunniford: And there’s one handy device in particular that’s aimed at helping you make sure you’re getting the best deal.

Julia Somerville: I’m the kind of person who breaks out into a cold sweat the minute anything like percentages are mentioned and I think you’ve got something there that could help.

Michael: Yes that’s right, sometimes if you’re in a shop with a percentage discount you may not have a calculator to hand to work out what the final price is. So on Skillswise we’ve developed a tool that you can simply slide up the price, slide down the discount, and it’ll tell you what the final price is.
