Give the step-by-step reasoning process and then the final answer. Carla has 6 sunflowers and 8 dandelions. The sunflowers have 9 seeds per plant and the dandelions have 12 seeds per plant. What percentage of Carla's seeds come from the dandelions?
First calculate the number of seeds from the sunflowers by multiplying the number of sunflowers by the number of seeds per sunflower: 6 sunflowers * 9 seeds / sunflower = 54 seeds. Next calculate the number of seeds from the dandelions by multiplying the number of dandelions by the number of seeds per dandelion: 8 dandelions * 12 seeds / dandelion = 96 seeds. Now add the number of seeds from each group of plants to find the total number of seeds: 54 seeds + 96 seeds = 150 seeds. Now divide the number of dandelion seeds by the total number of seeds and multiply the answer by 100 to find the percentage of seeds that come from the dandelions: 96 seeds / 150 seeds * 100% = 64%.
The final answer: 64.
