£50 with 20% off=£10.00 Sale price;£40.00
£40 with 10% off=£4.00 Sale price;£36.00
£55 with £20 off=£35.00 Sale price;£35.00

The cheapest offer is £55 with £20 off because I would be paying more money if I choose the other two offers.

My answer was £152.6p. these were the steps i used to answer that :
they have £50, so then you will £20. so then you would of added them all together which will equal £90. then you will do 10 x 4 which equals £40.then you will add 40 from 90 which will give you the answer £130.then you will look down at your money box list and it says 15. you do £130 add 15. this will equal £145. then add 7 ponds. this should equal £152. then you will add 6p which will give you £152.6p. whilst doing this you will have to add £4. so see your answer would be £152.6p.:) :)

this is how i worked it out.
20% of £50=£10
then do
£50-£10=£40
10% of £40=£4
£40-£4=£36
this is why £55 with £20 off is the cheapest offer.

The chocolate that costs £3.39 is the cheapest one because if you do 8×48=384 so that makes £3.84.So £3.84 is expensive than £3.39.

You have 1 £50 and two £20 so we can do £20×2=£40 to make it easy then we do £40+£50=£90.
Then we have four £10 so we do 4x£10=£40 we do £40 and £90 so we don’t have to add everything at once £40+£90=£130 then three £5 so we do 3x£5=£15
£130+£15=£145.Next we have seven £1 so do 7x£1=£7. Next add £145+£7=£152 we have eight 50p so 8x50p=£4 also £152+£4=156.Finally we have three 2p so times them, which equals 6p the answer is £156.06 we have an extra six.

£142 and 52p
I did 50+20+20+10+10+10+10+5+5+5+1+1+1+1+1+1+1=£142
And 50+2=52p

8. Muhammed Akinwale

20% of £50=£10
£50-£10=£40
10% of £40=£4
£40-£4=£36
£55-£20=£35
So that is why £55 with £20 off is the cheapest offer.
