Question

A tree farm initially has 150 trees. Each year, 20 trees are planted. How many trees will be there after 5 years?

1) 170
2) 180
3) 190
4) 200

Answer 1

After 5 years, there will be 250 trees on the tree farm, assuming 20 trees are planted each year starting with 150 trees. This calculation is done by multiplying 20 trees by 5 years and then adding the initial 150 trees, which is not reflected by any of the provided options.

Step-by-step explanation:

The question is asking us to calculate the number of trees on a farm over a period of 5 years given that the tree farm starts with 150 trees and 20 trees are planted each year. To solve this, we simply multiply the number of years by the number of trees planted each year and add the initial number of trees:

1. Multiply the number of trees planted each year (20) by the number of years (5).
2. Add the initial number of trees (150) to the result from step 1.

Using these steps:

1. 20 trees/year × 5 years = 100 trees
2. 150 trees + 100 trees = 250 trees

After 5 years, there will be 250 trees on the farm. This means that none of the provided options (170, 180, 190, 200) are correct.
