First bottle:
unit price .... £55/80 ml = 68.75 cents/ml
2nd bottle:
50 ml at £45 plus 50 ml at £22.50
or 100 ml for £67.50
unit price = £67.50/100 = 67.50 cents/ml
so what do you think?
Perfume is sold in two different sizes of bottle
The 80ml bottle is priced at £55
The 50ml bottle is usually priced at £45, but is on special offer
If you buy one 50ml bottle of perfume, you get a second for half price
By calculating the price per ml determine which offer is the best value for money, the 80ml bottle or the two 50ml bottles
You must show your working.
Thank you.

For the first bottle:
£55÷80= 0.6875
For the second bottle(s):
Since we're working out the price for two bottles, add the millilitres together. So:
50ml + 50ml = 100ml
Then add the prices together, considering the special offer.
The first bottle is at £45. The second is half price so, £45÷2= £22.50
Add the two together: £45 + £22.50= £67.50
Continue as normal, with the price divided by the amount:
£67.50÷100= 0.675
Now, the price of the first bottle per ml was 0.6875. The price for the second bottles was 0.675 altogether. The smaller number is the cheapest price, meaning it is the best buy. 0.675 is smaller than 0.6875
So, the two 50ml bottles are the better buy.
(The answer Reiny gave was correct but I thought it would be better to give reasons for each step to avoid confusion)

It was right so lit
Thanks for this answer
xzx
no you are all wrong
that answer gave 2/3 marks. is there something missing?
thanks Foster it was correct
unit price £55 80 ml = 68.75 cents ml
unit price = £67.50/100 = 67.50 cents/ml
£67.50÷100= 0.675
the two 50ml bottles are the best value for money.

You need to add a better conclusion and show the working. Thank you I sat there for two hours until I found ur answer. XX
*lowers defence and special defence*
80ml = £62.50 or 0.78125p/ml
100ml =£75 or 0.75p/ml
Therefore the two 50ml bottles are better value for money than the 80ml bottle
100ml =£75 or 0.75p/ml
Therefore the two 50ml bottles are better value for money than the 80ml bottle
thank u jo that works very well
