Let's start by using algebra to represent the problem.
Let x be the number of Norway spruces.
Then we know:
- There are 14 Scots pines
- There are twice as many Norway spruces as Scots pines (2x)
- There are seven times as many Sitka spruces as Scots pines (7 * 14 = 98)
To find the total number of trees, we can add up all three types:
Total number of trees = number of Scots pines + number of Norway spruces + number of Sitka spruces
Total number of trees = 14 + 2x + 98
Total number of trees = 2x + 112
We don't know the exact value of x, but we do know that it represents the number of Norway spruces. So, let's say x = 50 (this is just an example, it could be any number).
Then:
Total number of trees = 2(50) + 112 = 212
Therefore, if there are 14 Scots pines, twice as many Norway spruces (2x), and seven times as many Sitka spruces (98), there are 212 trees in the plantation.
In a plantation there are 14 scots pines twice as many Norway spruces and seven times as many sitka spruces.How many trees are there in the plantation
