Question

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

Answer 1

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.
