A coffee shop uses 4 liters of milk everyday. If they have 15 liters of milk in the refrigerator, after how many days will they need to purchase more?



Answer :

set up a proportion
4 liters/1 day=15 liters/x days
cross multiply
15=4x
divide
3.75=x
they would have to purchase more after 3 days, they would be 1 liter short of 4 days

Ok, so they use 4 liters of milk everyday

If they have 15 liters of milk in all then how many days will it take to use the milk up?

After one day, they have 11 liters of milk left over.

After two days, they have 7 liters of milk left over.

After three days, they have 3 liters of milk left over.

So on the third day, they need to call and make another order!

Hope this helps! :)
