In preparation for the maths festival you are asked to work out how much water the drinks area will need for the event. the arena buys drinks in 200 litre containers. each person is expected to drink 0.5 litre of water. the arena expects approximately 7,000 people to attend. estimate how many containers of water the arena will need to buy for the event?

Total liters of water needed = number of attendee x water                            consumption/attendee wherenumber of attendee = 7000 attendeewater consumption/attendee = 0.5litre of water/attendeetotal = 7000 x 0.5 litre        = 3500 litrescomputing the water requirement per 200 litre containerwater requirement in the event = 3500 litres/200 litre /container                                                  = 17.5 containersThe water requirement in the event at the arena of 7000 attendees is 17.5 containers.
