Problem Analysis

In the given problem, we are told that there are only roses and lilies in a flower bed. It is also mentioned that lilies make up two-ninths of all the plants in the flower bed, and there are 28 roses. We need to determine the total number of plants in the flower bed.

Solution

Let's assume the total number of plants in the flower bed is x.

According to the problem, lilies make up two-ninths of all the plants. So, the number of lilies can be calculated as (2/9) * x.

It is also mentioned that there are 28 roses. Therefore, the number of roses is 28.

To find the total number of plants in the flower bed, we can add the number of lilies and the number of roses:

(2/9) * x + 28 = x

Now, we can solve this equation to find the value of x.

Calculation

Let's solve the equation to find the value of x:

(2/9) * x + 28 = x

Multiply both sides of the equation by 9 to eliminate the fraction:

2x + 252 = 9x

Subtract 2x from both sides of the equation:

252 = 7x

Divide both sides of the equation by 7:

x = 36

Answer

Therefore, there are a total of 36 plants in the flower bed.
