Step-by-step explanation:

500ml. × 3 times when you get that you multiple it by the days and then takeaway

Hi! I’m pretty sure it’s 6 days. I think it’s 6 days because there are 1,000 Ml in one liter so if you multiply 1,000 X 9 it’s 9,000 and then divide it by 5 it’s 18 then divide it by 3 it’s 6. I hope this helps, Goodluck :)
