Question

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?

Answer 1

Based on the problem above, it is given that in every row, there are 36 spruce trees and there is a total of 9 rows. So 36 x 9, would be 324. There is a total of 324 spruce trees. And in each row, there are 14 blue spruce. So 36 - 14, there are 22 non blue spruce trees per row. So 22 x 9 rows, is equal to 198. Therefore, there are 198 spruce trees that are not blue.
