15 people can get water before the cooler is empty.
In order to find the number of people who would be able to get water before the cooler empties, you need to divide the total quantity of water in the cooler by the quantity given to each person.
To do that, both quantities have to have the same unit. The liters should therefore be converted to milliliters.
1 liter = 1,000 milliliters
7.5 liters = 7.5 x 1,000
= 7,500 milliliters
The number of people that would get a drink is:
= Quantity of water in cooler / quantity of water per person
= 7,500 / 500
= 15 people
