Final answer:
Sarah can make 20 liters of chili with 3 grams of her secret ingredient, using 0.15 grams per liter.
Step-by-step explanation:
To determine how many liters of chili Sarah can make with 3 grams of her secret ingredient, you can set up a simple division. Sarah adds 0.15 grams of her secret ingredient per liter of chili.
So, you divide the total amount of the secret ingredient (3 grams) by the amount used per liter (0.15 grams).
Here's the calculation:
Divide 3 grams by 0.15 grams to find the number of liters.
3 grams ÷ 0.15 grams per liter = 20 liters.
Therefore, with 3 grams of her secret ingredient, Sarah can make 20 liters of chili.
