Answer:
Yes, she is correct.
Explanation:
Given,
The depth she made in the ground for the plant = [tex]6\frac{7}{8}[/tex] inches,
Also, the height of the plant above the ground = 3.25 inches,
Hence, the total height of the plant = depth she made + height of the plant above the ground
[tex]=6\frac{7}{8}+3.25[/tex]
That is, the given expression is correct.
