1 meter = 100 cm
4 * 100 = 400
If there are 400 cm in 4 meters, we can use this equation to represent this problem:
d = day
4d = 400
Now, let's solve.
4d = 400
Divide both sides by 4.
d = 100
It will take 100 days for the sunflower to reach its maximum height of 4 meters/400 centimeters at 4 centimeters per day.
