This is quite simple. The only information we're given is that the tree grows at a rate of 3.1 cm a week. Because of this, we need a variable to create an equation, in this case the variable needs to be the amount of weeks that go by since the tree reaches 400 cm. Let's make this variable n. We ALSO need a variable for the height after n weeks. Let's make it h. Now to write the equation.
+h+=+400+%2B+3.1n+
Now to explain how I got this if it isn't quite clear yet. We are looking for the height, h, of the tree after a certain amount of weeks, n. We begin the measurements once the tree reaches 400 cm, hence the 400 being added to the 3.1n. Why 3.1? The tree grows at a rate of 3.1 cm a week.
