Answer:
Option A
Annette picked 50 roses from the garden
Step-by-step explanation:
Let us understand the problem, designating letters to represent unknown quantities.
Let the total number of roses = x
20% of the roses were red means that 20% of x = red
Since the number of red roses = 10,
we will have that 20% of x = 10
mathematically, we will have
[tex]\frac{20}{100} \times x = 10\\x= \frac{1000}{20}= 50[/tex]
hence, Annette picked 50 roses from the garden
