Answer: The plant grew 1.5cm each day
Step-by-step explanation:
Start by subtracting 57.5 and 20 to see how much it grew
[tex]57.5-20=37.5[/tex]
Now subtract 35 and 10 to see how many days it took to grow this long
[tex]35-10=25[/tex]
Finally, divide 37.5 and 25 to see how much it grew per day
[tex]\frac{37.5}{25} =1.5[/tex]
