The cost of 355 mL can of juice is $1.25 in vending machine. A 1.89 L carton of the same juice cast $3.89 at the grocery store.

1: Hou much would you save per mL if you bought juice from the grocery store instead of the vending machine?
(Hint: 1 L = 1000 mL)

Respuesta :

To solve this you need to calculate the cost per milliliter of both juices.
355ml costs 1.25. So if you divide the 1.25 by 355ml you will get the cost of 1 ml
The second you will have to convert L to ml by multiplying the L by 1000 (move decimal 3 places right)
use this value to calculate same as before.
find the difference between the two 1ml values to calculate your savings.
