Final answer:
To find the number of spruce trees that are not blue spruce, subtract the number of blue spruce trees from the total number of spruce trees in the tree farm.
Step-by-step explanation:
To find the number of spruce trees that are not blue spruce, we first need to determine the total number of spruce trees at the tree farm. We can do this by multiplying the number of rows by the number of spruce trees in each row: 9 rows * 36 spruce trees/row = 324 spruce trees in total.
Next, we need to determine the number of blue spruce trees in the tree farm. Since there are 14 blue spruce trees in each row and 9 rows, we can multiply these values to find the total number of blue spruce trees: 14 blue spruce trees/row * 9 rows = 126 blue spruce trees.
To find the number of spruce trees that are not blue spruce, we can subtract the number of blue spruce trees from the total number of spruce trees: 324 spruce trees - 126 blue spruce trees = 198 spruce trees that are not blue spruce.
