DerKrebs [107]

Answer:

4 plants

Step-by-step explanation:

In this problem, we are given the total area of the garden, which is:

A=10y^2

The number of plants that can fit inside the garden is given by the equation:

A=na

where:

n is the number of plants

a is the area of each plants

In this problem, the area of each plant is

a=2.5y^2

Therefore, we can re-arrange the equation to find the number of plants that can fit:

n=\frac{A}{a}=\frac{10}{2.5}=4
