Hint: Notice that the relationship between the different quantity does not change. e.g. no matter how many people are to be served, the number of chicken breasts is also twice the number tablespoons of olive oil and there are always three times more zucchinis than cloves of garlic.

 

You can use this to simplify your calculations e.g. if you calculate the quantity of tablespoons of olive oil, you will be able to find the number of chicken breasts by doubling that number.
