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

Second: 12 goes into 108: 9 times
Third: 9*2=18

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.
