Answer:
In 2014
Step-by-step explanation:
Blueberry bushes are planted in a field in the year 2009.
The blueberry bushes start to grow and cover the field in such a way that the area covered by the bushes doubles every year.
As per the given information we can say :
The field will be entirely covered with blueberry bushes by the year 2016.
So before one year, in 2015, they would be half covered that is 50% covered,
and even a year before that, in 2014, they would be covered half of 50%, that is 25%.
Therefore, the answer would be in 2014 field be covered 25% of the way.
