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.
unit price £55 80 ml = 68.75 cents ml
unit price = £67.50/100 = 67.50 cents/ml
the two 50ml bottles are the best value for money.
copy and paste that on m4ths w4tch
For the first bottle:
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:
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)
that answer gave 2/3 marks. is there something missing?
Thanks for this answer
thanks Foster it was correct
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
