Singapore Airlines A380 at LHR.
Since 2000, the A380 has won just 317 orders, less than a third of the 1,200 Airbus projected in its first 20 years.
Why is 317 less than a third of 1200?
Notes for Parents
Can your 11-year olds do mental arithmetic such as a third of 1,200?
Challenge your child to explain if Airbus is expected to meet its sales projection for the first 20 years.
