Final answer:
Qaylah should choose the third option where three quarters of the mixture is soda, which corresponds to a 1:3 ratio of apple juice to soda. For every 1 liter of apple juice, she should add 3 liters of soda.
Step-by-step explanation:
To find out which mixture Qaylah should choose to make the least appley drink, let's analyze the three given options:
- For each liter of soda, mix equal parts of apple juice, which gives us a 1:1 ratio.
- Mix apple and soda in a ratio of 2:3, which means for every 2 parts of apple juice, there are 3 parts of soda.
- Three quarters of the mixture is soda, and the rest is apple juice, which can be written as a ratio of 1:3 (1 part apple juice to 3 parts soda).
Comparing the ratios, option 3 has the least amount of apple juice because for every 1 liter of apple juice, she would need to add 3 liters of soda. This is because the ratio of apple juice to soda is 1:3.
