Question

What is the answer meyn?

Answer 1

the best value is two 50 ml bottles

Explanation:

Okay focus with me , if you buy a bottle of 50 ml you will get a second for half price so we can say that --> 2 bottles of 50 ml =

`45 + (45)/(2) = 67.5`

We get 100 ml with £67.5 just , but when you buy 80ml you must pay £55 Hum !

then you can dived the volume of bottle with price ...

• the price of one ml is 0.675 in first State

`(67.5)/(100 ) = 0.675`

• in the second state the price of one ml is

`(55)/(80) = 0.6875`

then :

`0.675 < 0.6875`

so the best value is two 50 ml bottles
