If a value is doubled, did it experience a 100% or a 200% increase?

It may seem like a silly question, because I was very confident the answer was 100%. However, it was marked incorrect on a test this week. The specific question was: The total grain production in 1950 was 40 kgper capita; In 1990 the total grain production was 80 kg per capita. What percent did it increase?
