Answer:
15 have no flowers, 6 have pink flowers, and 9 have red flowers.
Step-by-step explanation:
If we add the percentages we get 50%. That means half of the plants (15 of the 30) have no flowers.
Since we have taken away half of the plants, we have to double the percentages. So 20% becomes 40% and 30% becomes 60%.
So now we get 40% of 15, which is 6, and 60% of 15, which is 9.
Another way of doing the last step is just subtracting the 6 from the 15 to get the 9.
