Daisy is making lemonade with water and lemons. Based on the table below, how many lemons are needed for 24 oz. of water?

To determine how many lemons are needed for 24 ounces of water, we can look for a pattern in the relationship between the ounces of water and the number of lemons required based on the information provided in the table.

From the data we have:

- 18 oz of water → 3 lemons
- 42 oz of water → 7 lemons
- 60 oz of water → 10 lemons
- 66 oz of water → 11 lemons

We can analyze the relationships:

1. For the first segment (18 oz to 42 oz):
- From 18 oz to 42 oz (24 oz increase), the number of lemons increases from 3 to 7 (4 lemons increase).

So, for every 6 oz of water, 1 lemon is needed.

2. For the next segment (42 oz to 60 oz):
- From 42 oz to 60 oz (18 oz increase), the number of lemons increases from 7 to 10 (3 lemons increase).

So, for every 6 oz of water, 1 lemon is still a reasonable approximation.

3. For the last segment (60 oz to 66 oz):
- From 60 oz to 66 oz (6 oz increase), the number of lemons increases from 10 to 11 (1 lemon increase).

So, for every 6 oz of water, still, about 1 lemon is needed.

### To estimate for 24 oz:

From the 18 oz entry, we know:
- 18 oz needs 3 lemons.
- The difference from 18 oz to 24 oz is 6 oz.

Since we established that 6 oz requires 1 lemon:
- So, we need 3 lemons for 18 oz + 1 lemon for the additional 6 oz (to reach 24 oz).

Thus, for 24 oz of water, the total number of lemons needed is:
3 + 1 = 4 lemons.

Therefore, the answer is:

**A. 4**
