At a tree farm, there are 9 rows of 36 spruce trees. in each row, 14 of the spruce trees are blue spruce. how many spruce trees are not blue spruce?

In one row there are 36 spruce trees. 14 of these are blue spruce.
This means that in a row 36-14=22 are not blue spruce.

There are a total of 9 rows with 22 not blue spruce trees each, so in total there are:

not blue spruce trees.

198

First, let's find how many trees are not blue spruce in each row:
36 total spruce - 14 blue spruce = 22 non-blue spruce

There are 9 rows, so let's multiply that number by 9:
22 * 9 = 198 non-blue spruce
