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 atten

Total liters of water needed = number of attendee x water                            consumption/attendee
 where
number of attendee = 7000 attendee
water consumption/attendee = 0.5litre of water/attendee
total = 7000 x 0.5 litre
        = 3500 litres
computing the water requirement per 200 litre container
water requirement in the event = 3500 litres/200 litre /container
                                                  = 17.5 containers
The water requirement in the event at the arena of 7000 attendees is 17.5 containers.
