Final answer:
To calculate the percentage of tomatoes Camila picked, divide the number of tomatoes by the total number of vegetables and multiply by 100%. Camila picked 7 tomatoes out of a total of 20 vegetables, which is 35% when rounded to the nearest whole number.
Step-by-step explanation:
To find out the percentage of vegetables that were tomatoes, we first need to calculate the total number of vegetables Camila picked. She picked 4 carrots, 6 cucumbers, 3 peppers, and 7 tomatoes, which adds up to a total of 4 + 6 + 3 + 7 = 20 vegetables.
Now, we can calculate the percentage of tomatoes as follows:
Percentage of tomatoes = (Number of tomatoes / Total number of vegetables) × 100%
Percentage of tomatoes = (7 / 20) × 100% = 35%
After rounding to the whole number, the percentage of vegetables that were tomatoes is 35%.
