The cost of each cola per 100 ml is .10 cents each.
Step by step:
$2.64 divided by 8 is .33, meaning that it costs .33 cents per cola can.
You take .33 and divide it by 330 ml, because for one can, that is the how much each ml will cost. You will get .001 cent per ml.
Then you multiple .001 cent by 100 because that will be the cost of each ml times the ml you are looking for (100). You will get .10 cents.
Answer: The price per 100 ml of cola is .10 cents.
