Answer:
The number of : Spruce planted is 700
:Oaks planted is 1450
:Hemlocks planted is 2100
Step-by-step explanation:
Let the number of spruce planted = k
So,the number of hemlocks planted = 3k
And, the number of oaks planted = 50 + 2k
Total saplings planted = 4250
Now, Total saplings planted = Number of { spruce planted + oaks planted + hemlocks planted}
or, 4250 = k + 3k + (50 +2k)
⇒ 4250 - 50 = 6k
or, 6k = 4200
⇒ k = (4200 / 6) = 700 ⇒ k = 700
So, the number of spruce planted = 700
Number of Oaks planted = 50 + 2k = 50 + 1400 = 1450
ans, the number of hemlocks planted= 3k = 3 x 700 = 2100
