Lets assume P=10X and M=2X
P+M = 12X
NOW 12X =108
X = 9
2X=18 = M (C)

Let number of pines = 10x
................ magnolias= 2x

10x+2x= 108
12x= 108

x= \(\frac{108}{12}\)= 9

No of magnolias= 2x= 2*9= 18

\(Answer: C.\)

Total magnolias = (\(\frac{magnolias}{pines+magnolias}\)) * Total (magnolias+pines)=\(\frac{2}{(10+2)}\) * 84 = 18.

We can create the ratio pines : magnolias = 10x : 2x, and thus:

10x + 2x = 108

12x = 108

x = 9

Thus, there are 2 x 9 = 18 magnolias in the nursery.

Answer: C
