Answer:
What they are saying is that the plant is 10 meters tall and will grow .25 centimeters a month. They give the equation if the months is x. Then they say how many months there are, 15. So you have to multiply .25 by 15 then add that by 10 to get your height
Explanation:
H=10+(.25x15)
H=10+3.75
H=13.75
