Answer: The equation for the situation given would be: y = 2.5x + 195, where y is the height and x is the number of days past 60.
If you plug in 22 for x, you will have:
y = 2.5(22) + 195
y = 250
The height will be 250 cm 22 days after the 60th day. Now, compare this to the other sunflower and you will have your answer.
