## Instructions

- 1
Determine the overall number of drinks by multiplying the number of people attending the event by four. That means you need 600 total drinks for a party with 150 people. Most people drink about three drinks at a party. If you think your guests will drink more than that multiply by five or more.

- 2
Determine how many different kinds of drinks will be served.

- 3
Define the amount of a single drink for each type of drink that will be served. For example, a bottle of beer provides one drink, a 750ml bottle of wine provides about five drinks, and a 750ml bottle of hard alcohol is about 17 drinks.

- 4
Estimate the percentage of people that will want to enjoy each type of drink. For example, if you will serve beer, wine and hard alcohol, a common formula assumes that 50 per cent of the people will want beer, 25 per cent will want wine and 25 per cent will want hard alcohol.
