Well, let's say we start with 10 granola bars.
we take away 3 of them, so there would end up being 7 left.

Given :
After 4 days, a plant is measured to be 10 inches tall.
Later, after a total of 20 days, then height is measured to be 18 inches.
To Find :
The rate of growth for the plant.
Solution :
We know, rate is given by :

Therefore, rate of increase of height is 0.5 inch/day .
Hence, this is the required solution.
