Answer:
They have <u>18</u> vegetable plants.
Step-by-step explanation:
Given:
Emily's family loves to work together in the garden.
They have a. preference for flowers as 80% of their plants are flowers and the rest are vegetables.
They have 90 plants in the garden.
Now, to find the number of vegetable plants.
<u><em>Total plants in the garden = 90.</em></u>
80% of the plants are flowers.
So, number of plants which are flowers = 80% of 90.



<u><em>The number of flower plants = 72.</em></u>
Total plants = 90 (given)
So, to get the number of vegetable plants we subtract:

<u><em>Thus, vegetable plants = 18.</em></u>
Therefore, they have 18 vegetable plants.
