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. if they continue to grow in this way, the field will be entirely covered with blueberry bushes by the year 2016. when will the field be covered 25% of the way?

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.
